In humans, the autosomal gene S for baldness is dominant in men and recessive in. women. A woman with a bald brother

In humans, the autosomal gene S for baldness is dominant in men and recessive in. women. A woman with a bald brother and father marries a bald man. From this marriage, a normal son and an early bald daughter are born, who marries a normal man.
1) What are the genotypes of all members of this family?
2) What is the probability of the birth from this marriage of a son prone to early baldness?

1) Mother’s genotype – SsXX, father’s genotype – SsXY, son’s genotype – ssXY, daughter’s genotype – SSXX, daughter’s husband’s genotype – ssXY;
2) the probability of having a son prone to early baldness is 100%.
