Answer: The correct answer is 1/2

Explanation:

Based on Mendel's 2nd law - the law of independent assortment of genes - each character behaves as a separate unit and is INHERITED independently of any other character.

So, Aa will separate in two alleles "A" and "a". And by the law, each will be received by the gametes in equal rate of 50:50 i.e 1/2.

So for"A" allele, it is 1/2
