A woman who carries a recessive hemophilia gene has married a healthy man. Determine the genotypes of the parents, and the expected offspring – the ratio of genotypes and phenotypes.
1) Genotypes of parents ХН Хh and ХНУ;
2) offspring genotypes – ХН Хh, ХН ХH, ХН У, ХhУ; The ratio of genotypes 1: 1: 1: 1
3) daughters – the carrier of the hemophilia gene, healthy, and sons – healthy, sick with hemophilia. Phenotype ratio 2 (girls are healthy): 1 (boy is healthy): 1 (hemophilic boy)
