In humans, the recessive genes for color blindness and night blindness (“night blindness”) are linked to the X chromosome and are located

In humans, the recessive genes for color blindness and night blindness (“night blindness”) are linked to the X chromosome and are located at a distance of 40 morganids from each other. The webbing of the legs is inherited as a recessive trait linked to the Y chromosome. Brown eye color is the dominant autosomal trait, blue eye color is autosomal recessive. What kind of children and in what ratio can be expected from a marriage of a trigheterozygous brown-eyed woman and a heterozygous brown-eyed man with normal vision and webbed legs if:
1) in a woman, the genes for color blindness and night blindness are in the cis position (there is no crossing over);
2) in a woman, the genes for color blindness and night blindness are in a trans position (there is no crossing over);
3) in a woman, the genes for color blindness and night blindness are in the cis position (crossing over occurs);
4) are the genes for color blindness and night blindness in a woman in a trans position (crossing over occurs)?

1) From marriage of a heterozygous brown-eyed woman for three signs and a heterozygous brown-eyed man with normal vision and webbed legs, if a woman has genes for color blindness and night blindness in the cis position (there is no crossing over), brown-eyed girls with normal vision without webbed legs can be expected. blue-eyed girls with normal vision without webbed legs, brown-eyed boys with normal vision and webbed legs, brown-eyed color-blind boys with night blindness and webbed legs, blue-eyed boys with normal vision and webbed legs, blue-eyed boys with color blindness with night blindness and webbed legs 6: 2: 3: 3: 1: 1;
2) from marriage of a brown-eyed woman heterozygous for three signs and a heterozygous brown-eyed man with normal vision and webbed legs, if a woman has genes for color blindness and night blindness in the trans position (crossing over is absent), brown-eyed girls with normal vision without webbed legs can be expected. blue-eyed girls with normal vision without webbed feet, brown-eyed boys with normal color vision, night blindness and webbed feet, brown-eyed color-blind boys with normal night vision and webbed feet, blue-eyed boys with normal color vision, night blindness and webbed feet – color blind with normal night vision and webbed feet in a ratio of 6: 2: 3: 3: 1: 1;
3) from marriage of a heterozygous brown-eyed woman for three signs and a heterozygous brown-eyed man with normal vision and webbed legs, if a woman has genes for color blindness and night blindness in the cis position (crossing over occurs), 37.5% of brown-eyed girls with normal vision can be expected without webbed legs, 12.5% ​​blue-eyed girls with normal vision without webbed legs, 11.25% brown-eyed boys with normal vision and webbed legs, 11.25% brown-eyed color-blind boys with night blindness and webbed legs, 7.5% brown-eyed color-blind boys with normal night vision and webbed feet, 7.5% of brown-eyed boys with normal color vision, night blindness and webbed feet, 3.75% of blue-eyed boys with normal vision and webbed feet, 3.75% of blue-eyed boys with night blindness and webbed feet, 2.5% of blue-eyed color-blind boys with normal night vision and webbed feet, 2.5 % of blue-eyed boys with normal color vision, night blindness and webbed feet;
4) from marriage of a heterozygous brown-eyed woman for three signs and a heterozygous brown-eyed man with normal vision and webbed legs, if a woman’s genes for color blindness and night blindness are in a trans position (crossing over occurs), 37.5% of brown-eyed girls with normal vision can be expected without webbed legs, 12.5% ​​blue-eyed girls with normal vision without webbed legs, 7.5% brown-eyed boys with normal vision and webbed legs, 7.5% brown-eyed color-blind boys with night blindness and webbed legs, 11.25% brown-eyed color-blind boys with normal night vision and webbed feet, 11.25% of brown-eyed boys with normal color vision, night blindness and webbed feet, 2.5% of blue-eyed boys with normal vision and webbed feet, 2.5% of blue-eyed boys with night blindness and webbed feet, 3.75% of blue-eyed color-blind boys with normal night vision and webbed feet, 3.75 % blue-eyed boys with normal color vision, night blindness, and webbed feet.

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.
