Question

At a hypothetical locus, a man's genotype is Aa. What proportion of his gametes would be expected to receive the A allele?

a. All

b. 1/2

c. 3/4

d. 1/4

e. None

Answer 1

it is B. 1/2

This is beacuse automatically 1/2 of his gametes get (A) and the other half get (a).

It is kind of like you split his genotype in half therefore getting a half each.

Answer 2

b. 1/2

the person is carrying a heterozygous character and so the gametes will carry A or a at a ratio 1:1 therefore the proportion is half.
