Hello, favismosis is an incomplete dominant sex-linked genetic disease, and the pathological gene is on the X chromosome. It is similar to red-green color blindness. If both parents are normal, the son may also be color blind.

The son receives the Y chromosome from the father and an X chromosome from the mother. If the mother is a carrier of the disease gene, that is, one X chromosome of the mother is normal and the other X chromosome has the disease gene, then the mother is normal. , and the son may be sick.

The daughter receives one X chromosome from her father and one from her mother. As long as her father is normal, she will have a normal X chromosome and will not get sick. Therefore, men are more susceptible to the disease.

Therefore, if both parents do not have favismosis, the child will not get it. Now this disease has been listed as an inspection-free item in some cities and can be identified.
