> there is a 50% chance that a sibling will also be a carrier if the parents are both carriers. if one parent is a carrier, than there is a 50% chance of your sister being a carrier. if both parents are carriers, there is a 50% of your sister being a carrier, a 25% chance of her not being a carrier, and 25% chance of her having the disease. so i'm correct again, faggot.    > a disease that is more likely to be expressed if you inbreed only if you're a carrier, retard. what is your probability of being a carrier?   why do you think some groups have more carriers than other? you stupid fucking nigger. if you don't have some mechanism to remove negative mutations, they will build up until everyone is a carrier of everything. you're like a million times more likely to have a negative mutation than a positive one.
