If a plant is an autotetraploid with the genotype A₁A₁A₂A₂,what is the frequency of offspring with the genotype A₁A₁A₁A₁ following self-fertilization of the plant?
A)1/2
B)1/4
C)9/16
D)8/36
E)1/36

Quizplus · Accepted Answer

In an autotetraploid, each parent can produce gametes with combinations of two alleles. The probability of getting A₁A₁ from one parent is 1/6. Thus, the probability of A₁A₁A₁A₁ offspring is (1/6) * (1/6) = 1/36.
