What are the genotypes and phenotypes of the parents?
How many children do not have dimples?
What could be the genotypes of the children who have dimples?

Answer

Genotypes and Phenotypes of the Parents: The father has dimples, so his phenotype is 'dimples'. His genotype could be either homozygous dominant (DD) or heterozygous (Dd). The mother does not have dimples, so her phenotype is 'no dimples', and her genotype is homozygous recessive (dd).

Number of Children Without Dimples: There is 1 child without dimples, as indicated by the unfilled circle.

Genotypes of the Children with Dimples: The children with dimples could have the genotype Dd, as they must inherit one dominant allele from the father and one recessive allele from the mother.
