Consider a gene with four alleles A₁, A₂, A₃, and A₄. In the cross A₁A₂ × A₃A₄, how many offspring genotypes are possible? A)2 B)3 C)4 D)5 E)6

Question

Quizplus · Accepted Answer

To determine the number of possible genotypes in the offspring, we need to use the FOIL method. F = A₁, O = A₂, I = A₃, and L = A₄. Possible offspring genotypes are: FO, FOI, FOIL, OI, OIL, and IL. This gives us a total of 6 possible genotypes, so the correct answer is (C) 4.
