A man with signs of polydactyly married a woman with normal bone structure.

A man with signs of polydactyly married a woman with normal bone structure. They had a child with normal bone structure, but suffering from galactosemia. Determine the genotype of all family members.

M – healthy
m – polydactyly
T – galactosemia
t – norm
R: wives. MMTt * husband. mmtt
gametes: MT Mt; mt
F1: MmTt (healthy with galactosemia); Mmtt (healthy)
Based on the conditions of the problem, the genotypes of the parental individuals are: MMTt – healthy woman, mmtt – polydactyly.
In the offspring, genotype and phenotype 1: 1 splitting occurs. The genotype of a child with galactosemia is MmTt
