Question

This states that the alleles of different genes separate independently of one another during the formation of gametes IF they are located on separate chromosomes. What is this principle called?

A) Law of Dominance
B) Law of Segregation
C) Law of Independent Assortment
D) Law of Incomplete Dominance

Answer 1

Mendel's law of independent assortment states that genes do not influence each other with regard to the sorting of alleles into gametes, and every possible combination of alleles for every gene is equally likely to occur.

Step-by-step explanation:

Mendel's law of independent assortment states that genes do not influence each other with regard to the sorting of alleles into gametes, and every possible combination of alleles for every gene is equally likely to occur. Independent assortment of genes can be illustrated by the dihybrid cross, a cross between two true-breeding parents that express different traits for two characteristics. Consider the characteristics of seed color and seed texture for two pea plants, one that has wrinkled, green seeds (rryy) and another that has round, yellow seeds (RRYY). Because each parent is homozygous, the law of segregation indicates that the gametes for the wrinkled-green plant all are ry, and the gametes for the round-yellow plant are all RY. Therefore, the F₁ generation of offspring all are RrYy (Figure 8.10).
