In humans, glaucoma is inherited as an autosomal recessive trait (a). The wife suffers from glaucoma, and the husband is heterozygous for this trait. Determine the genotypes of the parents and the likelihood of having a healthy baby.
1. Genotypes and phenotypes of P: Mother – aa – with glaucoma, father – Aa – normal vision;
2. Genotypes and phenotypes of offspring: Aa – normal vision, aa – with glaucoma;
3. The probability of having healthy children is 50%.
Answer: mother – aa, father – Aa, probability – 50.
