In humans, the fine hair gene does not completely dominate (A) over the straight hair gene (a), i.e. wavy hair is an intermediate feature (Aa). A woman with fine hair marries a man with straight hair. Determine the genotypes of all family members by trait. What is the probability (%) of children with fine hair in this family?
1. Genotypes and phenotypes of P: both mother AA and father – aa
2. Genotypes and phenotypes of offspring: Aa – wavy hair 100%;
3. The probability of having children with fine hair is 0%.
Answer: mother – AA, father – aa, probability – 0.
