Which disease is more common in males than females?

Which disease is more common in males than females?

  • (A) Heart attack
  • (B) Dementia
  • (C) Color blindness
  • (D) Hypertension
Color blindness is much more common in men because it is associated with an X-linked recessive gene. Guys have only one X chromosome, which is XY. If that one X chromosome has the defective gene, then color blindness occurs. Women have two X chromosomes, which are XX. If one of the X chromosomes has the defective gene, then they won’t be color blind because the other gene will override it, unless both X chromosomes have the defective gene.
