In healthy parents, the son has hemophilia. Determine the genotypes of the parents, their son, the probability of giving birth

In healthy parents, the son has hemophilia. Determine the genotypes of the parents, their son, the probability of giving birth to sick children and carriers of the hemophilia gene in these parents if the hemophilia gene (h) is recessive and sexually linked.

1) Genotypes of parents: mother – ХН Хh, father – ХHY;
2) the genotype of the son – XhY;
3) the probability of the appearance of sick children – 25% (sons), 25% carriers of the hemophilia gene (daughter)
