One parent has one copy of a dominant allele for Gene 87 and one recessive allele for Gene 87.The other parent has two copies of the dominant allele for Gene 87.What is the chance that their children will inherit the recessive condition (two copies of Gene 87)? You may need to draw a Punnett square to figure this out.

Since one parent is heterozygous (carrying one dominant and one recessive allele) and the other parent is homozygous dominant (carrying two dominant alleles), all offspring will receive at least one dominant allele, making it impossible for any child to inherit two recessive alleles for the condition.
