are there higher percentages of genetic illnesses found in the female population?
Actually, it is the male population that will exhibit more of certain genetic illnesses (hemophilia, for one)
The female will often be the one to carry genetic illnesses and the male will acquire it
This is because defects in the X chromosome can be overcome in the female with the other x chromosome making up for the defect. However, in the male, if they inherit an x chromosome that carries the genetic illness, they don't have another x chromosome to pick up the job and correct for the defective chromosone
Males are XY and their Y chromosome won't have the ability to overcome the x defect
