In humans, the recessive gene for hemophilia is linked to the X chromosome, the gene for general color blindness is localized

In humans, the recessive gene for hemophilia is linked to the X chromosome, the gene for general color blindness is localized in the homologous regions of the X and Y chromosomes. Determine which children can be born from marriage:
1) a woman who is heterozygous for general color blindness – carriers of color blindness (genes are in the cis-position) and heterozygous for general color blindness (a recessive gene is localized in the Y-xpo-mosome) men with normal blood clotting;
2) women – carriers of color blindness with general color blindness and heterozygous for general color blindness (the recessive gene is localized in the X chromosome) of a hemophilic man.

1) From the marriage of a woman who is heterozygous for general color blindness – a carrier of color blindness and a man who is heterozygous for general color blindness with normal blood clotting, girls with normal and color vision and blood clotting can be expected and boys who are color blind and hemophilic in a ratio of 3: 1;
2) from the marriage of a woman who is a carrier of color blindness with general color blindness and a hemophilic man who is heterozygous for total color blindness, one can expect color-blind girls with normal blood clotting, boys with normal color vision and blood clotting, and color-blind and hemophilic boys in a 1: 1 ratio :1.

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.
