Emelia Lane · Answer 1

When a parent is described as heterozygous, that means that they have one dominant allele and one recessive. If both are heterozygous, both parents have a genotype (allele combination) of Yy.

The Punnett square would look as appears in the photo, and the genotypes of the offspring are as depicted (two with Yy allele combinations, one with YY, and one with yy).
