What Does the law of Independent Assortment tell us?

What Does the law of Independent Assortment tell us?

The Principle of Independent Assortment describes how different genes independently separate from one another when reproductive cells develop. During meiosis, the pairs of homologous chromosome are divided in half to form haploid cells, and this separation, or assortment, of homologous chromosomes is random.

Which best describes the law of Independent Assortment?

Answer Expert Verified The law of independent assortment was first introduced by a biologist named George Mendell. It stated that when two or more characteristics are inherited, independent assortment would happen and there would be an equal opportunity for both traits to occur together.

What is the effect of law of Independent Assortment?

In effect, the Law of Independent Assortment creates a large amount of variety based on different combinations of genes which have not previously occurred. In one instance, genes cannot be assorted completely randomly. This occurs with linked genes, or genes which share the same chromosome.

What is an example of independent assortment?

Example: Pea color and pea shape genes. Let’s look at a concrete example of the law of independent assortment. When Mendel did this cross and looked at the offspring, he found that there were four different categories of pea seeds: yellow and round, yellow and wrinkled, green and round, and green and wrinkled.

What is Mendel’s Second law of Independent Assortment?

Mendel’s 2nd law states that during gamete formation the segregation of each gene pair is independent of other pairs. Mendel’s 2nd law is often referred to as the principle of independent assortment. Both of Mendel’s laws are about segregation, which is the seperation of allele pairs.

What best describes Mendel’s law of segregation?

Mendel’s Law of Segregation states that a diploid organism passes a randomly selected allele for a trait to its offspring, such that the offspring receives one allele from each parent.

Why is the law of Independent Assortment important?

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.

What is Law of Independent Assortment give example?

A good example of independent assortment is Mendelian dihybrid cross. The presence of new combinations – round green and wrinkled yellow, suggests that the genes for the shape of the seed and color of the seed are assorted independently.

Why Law of Independent Assortment is not universal?

Most of the genes are linked, they are situated on one chromosome. Hence, in the form of linkage groups, they pass through the gametes. This is why the law of independent assortment is not applicable universally. …

How does Law of Independent Assortment increase variation?

The Law of Independent Assortment states that separate genes for separate traits are passed independently of one another from parents to offspring. Together with random fertilization, more possibilities for genetic variation exist between any two people than the number of individuals alive today.

What is Mendel’s first law of segregation?

The segregation law is Mendel’s first law. It states that during meiosis alleles segregate. During the process of meiosis, when gametes are formed, the allele pairs segregate, i.e. they separate. For the determination of a Mendelian trait, two alleles are involved — one is recessive and the other is dominant.

What best describes the law of independent assortment?

Law of Independent Assortment Definition. The Law of Independent Assortment is a principle of inheritance that states that each heritable allele (form of a gene) is inherited independently of one another.

What are Mendel’s 3 laws?

Mendel’s studies yielded three laws of inheritance: the law of dominance, the law of segregation, and the law of independent assortment. Each of these can be understood through examining the process of meiosis .

What statement explains Mendel’s law of segregation?

Gregor Mendel’s law of segregation states that the two alleles for each trait segregate, or separate, during the formation of gametes, and that during the formation of new zygotes, the alleles will combine at random with other alleles. The law of segregation ensures that a parent, with two copies of each gene, can pass on either allele.

What are examples of Mendel law?

Mendel’s law of segregation describes what happens to the alleles that make up a gene during formation of gametes . For example, suppose that a pea plant contains a gene for flower color in which both alleles code for red. One way to represent that condition is to write RR, which indicates that both alleles (R and R) code for the color red.
