? Six fingers disease is a sex chromosome dominant genetic disease with high genetic probability. If the patient is a male, the incidence of the offspring born with a normal woman is 50% (the boy is normal and the girl is a six-fingered patient). If the patient is female, then the offspring born to him and a normal male may be 100% or 50% hereditary. Now the plastic surgery technology is developed, and six fingers can be removed by surgery, and the function will not be affected after surgery, and it can basically return to normal.
