The corn can be used to study the law if independent assortment as each kernel of the corn is its fruit. Thus, it is a result of sexual reproduction. OR (i) In case of corn, in addition to this there can be a pure line trait which can be found in corn. (ii) However Mendel used Garden pea for his experiment,we can use corn because it is similar to character with that of Garden pea. (iii) While doing the experiment with corn we found out that there is independent and random assortment of the different gametes. Author Posts

Can be used to explain the law of Independent Assortment?

The principle or law of independent assortment can be studied by means of dihybrid cross, e.g., between pure breeding pea plants having yellow round seeds (YYRR) and pure breeding pea plants having green wrinkled seeds (yyrr). So, the correct answer is ‘Dihybrid’.

What is the law of Independent Assortment give its ratio with example?

F2 generation: Completion of the Punnett square predicts four different phenotypic classes of offspring, yellow/round, yellow/wrinkled, green/round, and green/wrinkled, in a ratio of 9:3:3:1. This is the prediction of the model in which the seed shape and seed color genes assort independently.

What is Mendel’s law of Independent Assortment?

Key Points –

  • Mendel’s law of independent assortment states that genes do not influence each other with regard to the sorting of alleles into gametes; every possible combination of alleles for every gene is equally likely to occur.
  • The calculation of any particular genotypic combination of more than one gene is, therefore, the probability of the desired genotype at the first locus multiplied by the probability of the desired genotype at the other loci.
  • The forked line method can be used to calculate the chances of all possible genotypic combinations from a cross, while the probability method can be used to calculate the chance of any one particular genotype that might result from that cross.

Which of the following statements is an example of independent assortment?

Statement A tall pea plant is no more or less likely to have round seeds than a dwarf pea plant is an example of independent assortment because in the cross between tall and dwarf pea plants, the gene for round seeds will go into both the tall and dwarf plants and both the geenes for tallness and shape of the seed are

What is Independent Assortment and how does it work?

The idea behind independent assortment is that genes are inherited independently of one another. In other words, the genetic factors that control crest and sex are physically separate. Because the genetic factors are physically separate, they segregate independently during gamete (egg and sperm) formation.

What is the Mendel’s law explain with an example?

Monohybrid Cross – In this experiment, Mendel took two pea plants of opposite traits (one short and one tall) and crossed them. He found the first generation offspring were tall and called it F1 progeny. Then he crossed F1 progeny and obtained both tall and short plants in the ratio 3:1.

What does independent assortment mean simple?

Principle of Independent Assortment – What does independent assortment mean? The law of independent assortment means that separate traits of different alleles are inherited by the zygote independently from each other. Where the random selection of one allele for a certain trait is not connected by any means to the selection of another allele for a different trait.

What is an independent assortment? Independent assortment states that the inheritance of various genes occurs independently of each other. In the law of independent assortment, the combination of genes and their probability is calculated and assumed by multiplying the probabilities of each gene. Moreover, the probability of having one gene does not influence the probability of having the other.

What stage of meiosis does independent assortment occur? Independent assortment in meiosis takes place in eukaryotes during metaphase I of meiotic division. It produces a gamete carrying mixed chromosomes. Gametes contain half the number of regular chromosomes in a diploid somatic cell.

Thus, gametes are haploid cells that can undergo sexual reproduction at which two haploid gametes are fused together forming a diploid zygote having the complete set of chromosomes. The physical basis is the random distribution of chromosomes during the metaphase in relation to other chromosomes. Why is independent assortment important? Independent assortment is responsible for the production of new genetic combinations in the organism along with crossing over.

Thus, it contributes to genetic diversity among eukaryotes. To define independent assortment, you should understand the law of segregation first. The law of segregation states that in meiosis, different gamete cells get two different independently assorted genes.

  • On the other hand, the two maternal and paternal DNA are randomly separated allowing for more diversity in genes.
  • The law of independent assortment is apparent during the random division of the maternal and paternal DNA sources.
  • Due to random assortment, the gamete may get maternal genes, paternal genes, or a mixture of both.

The genetic distribution is based on the initial stage of meiosis where these chromosomes are lined up randomly.

What is the law of Independent Assortment explain with an example Brainly?

Answer: The law of independent assortment states that the alleles for a trait separate when gametes are formed. These allele pairs are then randomly united at fertilization. These cross-pollination experiments were performed with pea plants that differed in one trait, such as the color of the pod. Explanation: please as your wish can you follow me please mark me as brainliest

Where does independent assortment occur?

The reason for independent assortment – To see why independent assortment happens, we need to fast-forward half a century and discover that genes are physically located on chromosomes. To be exact, the two copies of a gene carried by an organism (such as a Y and a y allele) are located at the same spot on the two chromosomes of a homologous pair,

  • Homologous chromosomes are similar but non-identical, and an organism gets one member of the pair from each of its two parents.
  • The physical basis for the law of independent assortment lies in meiosis I of gamete formation, when homologous pairs line up in random orientations at the middle of the cell as they prepare to separate.

We can get gametes with different combos of “mom” and “dad” homologues (and thus, the alleles on those homologues) because the orientation of each pair is random. To see what this means, compare chromosome arrangement 1 (top) and chromosome arrangement 2 (bottom) at the stage of metaphase I in the diagram below. Explain How Corn Can Be Used As An Example Of Mendel Image modified from ” The laws of inheritance: Figure 5,” by OpenStax College, Concepts of Biology, CC BY 4.0 Genes that are on different chromosomes (like the Y and R genes) assort independently. The seed color and seed shape genes are on chromosomes 1 and 7 of the pea genome, respectively, in real life 1, Explain How Corn Can Be Used As An Example Of Mendel There are, however, gene pairs that do not assort independently. When genes are close together on a chromosome, the alleles on the same chromosome tend to be inherited as a unit more frequently than not. Such genes do not display independent assortment and are said to be linked, We’ll take a closer look at genetic linkage in other articles and videos.

Which best describes the law of Independent Assortment quizlet?

Which statement best describes Mendel’s law of independent assortment? The inheritance of one trait does not affect the inheritance of another trait.

Which best describes the process of independent assortment?

Which best describes the process of independent assortment? The way one pair of homologues lines up along the metaphase plate does not affect how any other pair lines up.

Which of the following statements supports the law of independent Assortment?

Gregor Mendel’s law of independent assortment states that when genes are inherited, they are inherited independent of each other. This leads to the formation of new combinations and not always the same as the parental characteristics. In other words, it produces variation in the progeny.

How does meiosis explain Mendel’s Laws of Segregation and independent Assortment?

Brent Cornell Gregor Mendel was a 19th century Moravian monk who demonstrated that the inheritance of traits (i.e. genes) follow particular laws:

Law of Segregation: Each hereditary characteristic is controlled by two alleles which separate into different gametes Law of Independent Assortment: The separation of alleles for one gene is independent to allele separation for another gene Principle of Dominance: In pairs of alleles that are different, one allele will mask the effect of the other allele

These ‘laws’ are now known to be due to key events that occur during meiotic division:

The law of segregation describes how homologous chromosomes (and hence allele pairs) are separated in meiosis I The law of independent assortment describes how homologous pairs align randomly (as bivalents) during metaphase I

Through the elucidation of the process of meiosis, we now know that there are certain exceptions to Mendel’s laws:

What is the law of Independent Assortment in biology quizlet?

The Law of Independent Assortment states that alleles for separate traits are passed independently of one another from parents to offspring. That is, the biological selection of an allele for one trait has nothing to do with the selection of an allele for any other trait.

What is Independent Assortment and when does it occur quizlet?

Independent assortment is the random sorrting of chromosomes, during the making of gametes. it ends up being individual gametes. crossing over. crossing over is chromosomes come together and can become twisted, and they pull apart which causes them to break, rearange then reattach.

What was used to discover the law of Independent Assortment?

Independent Assortment in Mendel’s Experiments – Gregor Mendel performed many experiments involving breeding pea plants. In doing so, he gleaned information about how “units of heredity” work, which would later on become known as genes after DNA was discovered and determined to be the material that encodes genetic information.

Mendel developed the Law of Independent Assortment after breeding two different pea plants with two different characteristics; he bred plants with yellow, round peas with plants that had wrinkled, green peas. Since yellow and round were dominant over wrinkled and green, all the offspring had yellow, round peas.

But, when this first generation was crossbred with each other in a dihybrid cross, there was a lot of variation in the second generation. Peas were no longer either just yellow and round or green and wrinkled; some were green and round, while some were yellow and wrinkled.

Furthermore, the offspring showed their characteristics in a ratio of 9:3:3:1. Nine were round and yellow, three were round and green, three were wrinkled and yellow, and one was wrinkled and green. This ratio stayed the same even when hundreds of dihybrids were crossed. This occurred because each of the parent plants only gave their offspring one allele and because yellow and round were dominant traits and masked the green and/or wrinkled traits in certain individual plants.

The diagram below depicts Mendel’s dihybrid cross. Mendel’s experiment showed that the alleles for round or wrinkled peas were inherited independently from the alleles for yellow or green peas since the plants were not just round and yellow or green and wrinkled. We now know that they exist on different chromosomes, which allows them to be mixed up during the process of meiosis.

Which best describes the law of Independent Assortment quizlet?

Which statement best describes Mendel’s law of independent assortment? The inheritance of one trait does not affect the inheritance of another trait.

What is true of law of Independent Assortment Mcq?

Mendel’s Law Of Independent Assortment – Definition – Mendel’s Law of Independent Assortment states that “When alleles of more than one trait are followed together in the cross, the alleles of these traits assort independently to each other during gamete formation”.
