Although often viewed as the stronger sex, explain why males are actually more vulnerable
What will be an ideal response?
Answer: Because the sex chromosome of females is composed of two Xs, if one of these Xs contains a recessive gene for a disorder or disease, it will not manifest itself due to the other X overriding it and not allowing it to be expressed. Since the sex chromosome makeup of the male is XY, if there is a recessive gene for a disorder on his X chromosome, it will express itself because there is not another X chromosome that may contain a dominant gene to block its expression.
