| In humans, glaucoma is inherited as an autosomal recessive trait (s). The wife suffers from a family whose family never met glaucoma (pure line), and the husband is heterozygous for this trait, his mother suffered from glaucoma. Determine the genotypes of the parents and the likelihood of having a baby with glaucoma.
1. Genotypes and phenotypes P: Mother – AA — normal vision; father – Aa – because his mother suffers from glaucoma, and by condition it is said that he is heterozygous;
2. Genotypes and phenotypes of offspring: AA – normal vision, Aa – normal vision;
3. The probability of having healthy children is 100%; with glaucoma – 0%.
Answer: mother – AA, father – Aa, probability – 0.
