In humans, the inheritance of albinism is not sex-linked (A is the presence of melanin in skin cells, and the absence of melanin in skin cells is albinism), and hemophilia is sex-linked (XH is normal blood coagulation, Xh is hemophilia). Determine the genotypes of the parents, as well as the possible genotypes, gender and phenotypes of children from the marriage of a dihomozygous normal albino woman with hemophilia for both alleles
1) parental genotypes: (M) AAXHXH (gametes AXH); (O) aaXhY (gametes aXh, aY);
2) genotypes and gender of children: (M) AaXHXh; (O) AaXHY;
3) phenotypes of children: outwardly normal girl on both alleles, but a carrier of the genes for albinism and hemophilia; outwardly normal boy on both alleles, but a carrier of the albinism gene
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
