A discussion came to surface in my Biology II AP class about heredity and sex linked characteristics. Now with a female carrying two X gametes and a male containing an X and Y gamete, males are more prone to inherit sex linked characteristics such as red-green color blindness and hemophilia. The reason so being because in order for a female to inherit the disease she would have to have the traits on both of her X gametes, meaning that her mom would have to be a carrier or have it while her dad had it. Otherwise, if she has just one X chromosome with the trait she is only a carrier. The reason a male is so prone to inheritence of these traits is because he only needs his X chromosome to contain the trait in order for it to be expressed. My question is, is it possible for a male to be a carrier while having the gene unexpressed? You never know with science...most times there are exceptions. So if anyone knows the answer please reply. Thank you.
