Mendel's Law of Independent Assortment. To this point we have followed the expression of only one gene. Mendel also performed crosses in which he followed the segregation of two ... The phenotypes and general genotypes from this cross can be represented in the ... Let's use theexample of the yellow,

Each kernel of corn inherits traits independently. Each kernel of corn receives one allele from each parent for the traits of color and texture. Corn can have multiple kernel colors because each kernel is independently formed.

Answer:

12 : 3 : 1

Explanation:

According to Mendel's principles, a dihybrid cross between two heterozygous summer squash parents (WwGg X WwGg) should yield offsprings, 12 with white, 3 with yellow and 1 with green color phenotype. The classic Mendelian phenotypic ratio for dihybrid cross is 9:3:3:1. In this case, genotypes W- G- and W- gg produce white color phenotype. This is because we have 12: 3: 1 phenotypic ratio in which the alleles of two different genes assort independently into gametes.

Dihybrid cross for heterozygous summer squash:

WG Wg wG wg

WG WWGG WWGg WwGG WwGg

Wg WWGg WWgg WwGg Wwgg

wG WwGG WwGg wwGG wwGg

wg WwGg Wwgg wwGg wwgg

Genotypes:

W-G- and W- gg = white = 12

ww G- = yellow = 3

ww gg = green = 1
