The genotype Aagg is not possible in the offspring. It is due to gamete combinations.
Gamete combination refers to the presence of particular alleles in the gametes of a genetic cross.
Gamete combination largely determines the possible genotypes and phenotypes observed in offspring.
In this case, one parent does not have the allele referred as 'g' and therefore the offspring cannot be homo-zygous for this allele.
