Sveta always wanted to have the same “dimples” on her cheeks like her mother’s (dominant sign (A) is not sex-linked). But Sveta had no dimples, like her father. Determine the genotypes of family members based on the presence or absence of “dimples”
Because the dominant feature is the presence of “dimples”, but the girl and her dad do not have this feature, which means they are recessive homozygotes and their genotype aa. The mother has “dimples” – A_, but her daughter does not have this trait, which means that the mother is heterozygous for the trait: Aa.
Answer: Mother – Aa; father – aa; daughter – aa.
