Work out the cross

Dear Student,

Haemophilia is a hereditary condition that affects the body's ability to form blood clots. It's an X-linked recessive condition.

a. if a hemophilic man marries a normal woman-


Thus, the boys will be normal, and the girls will be the carrier.

b. if their daughters marry normal men-


Thus, when the carrier daughters marry normal men, the girls born may be normal or carrier, and the boys may also be hemophilic or normal.

Regards,

Dear student,

Haemophilia is a defect of blood which prevents its clotting. It is caused by a recessive gene located in the X-chromosome. When a haemophilic man (XhY) marries a normal woman (XX), produces carrier girls (XXh) and normal boys (XY), i.e. all their offsprings will be normal.

Regards.
