Wheat kernel color is an additive trait controlled by two genes, gene A and gene B. The A1 and B1 alleles add 1 unit of color to the kernels. The A2 and B2 alleles add 0 units of color to the kernels. Question 1:If you crossed a dihybrid (A1A2 B1B2) individual to a A2A2 B2B2 individual, which of the following phenotypes are possible?a. 0 units (white)b. 1 unit (light pink)c. 2 units (dark pink)d. 3 units (light red)e. 4 units (dark red) Question 2:If you crossed a dihybrid (A1A2 B1B2) individual to a A2A2 B2B2 individual, what is your expected phenotypic ratio?a. 1:2:1b. 1:1:1:1c. 9:3:3:1d. 3:1

Question

Wheat kernel color is an additive trait controlled by two genes, gene A and gene B. The A₁ and B₁ alleles add 1 unit of color to the kernels. The A₂ and B₂ alleles add 0 units of color to the kernels.

Question 1:

If you crossed a dihybrid (A₁A₂ B₁B₂) individual to a A₂A₂ B₂B₂individual, which of the following phenotypes are possible?

a. 0 units (white)

b. 1 unit (light pink)

c. 2 units (dark pink)

d. 3 units (light red)

e. 4 units (dark red)

Question 2:

If you crossed a dihybrid (A₁A₂ B₁B₂) individual to a A₂A₂ B₂B₂individual, what is your expected phenotypic ratio?

a. 1:2:1

b. 1:1:1:1

c. 9:3:3:1

d. 3:1
