If the genotype of both parents was Aa, what would be expected of the genotypes among their possible offspring? Half would have
the genotype AA. Half would have the genotype Aa. Three-quarters would have the genotype aa. Three-quarters would have the genotype Aa.

Answer:
The correct answer would be "Half would have the genotype Aa".
The genotype of both parents is Aa. So, each of them would produce two types of gametes one of which contains A and other would contain a.
The cross would produce offspring with three possible types of genotypes AA, Aa, and aa in the ratio 1:2:1.
Thus, one-fourth of the offspring would have genotype AA, two-fourth or half of the offspring would have the genotype Aa, and one-fourth would have aa.

Explanation:
For each heterozygous parent with the genotype BbRr, the possible gametes are: BR, Br, bR, and br. A set of these gametes from one of the parents will be lined up along the top of the Punnet's square while another set from the other parent will be lined up along the side of the square.
The result is shown in the attached image.
