Answer:
0
Explanation:
Heterozygous means that they have an allele for both traits and is in the form (Aa) meaning they have both the dominant and recessive trait.
We notice that the third trait, represented by 'g', is in the form gg for both individuals. Since they are both lowercase and the same allele, they are both hom0zygous for that trait, meaning there is no way the offspring can get a dominant trait to make their genotype Gg.
