  2. AA
  3. aa
  4. aA

hintHint:

Genotype of offspring is obtained by crossing the genes present in the left column with the genes in the upper row of the Punnett square.

The correct answer is: AA


    • In a Punnett square, the upper row represents alleles for the female gametes.
    • The left column represents the alleles for the male gametes
    • In the given Punnett square, the cross between male allele A and female allele A produces offspring with genotype of AA.
