Correct.
I think I get this, but just want to make sure:
Quest reads. The gene for albinism in humans is recessive, meaning that carriers of this gene have a probability 1/2 of passing it to a child., and the child is albino only if both parents pass the albinism gene. Parents pass their genes independently of eachother.
1) If both parents carry the albinism gene, what is the probability that their first child is albino?
2) If they have 2 children (who inheret independently of eachother), what is the probability that both are albino... 3)that neither are albino.
My answers?
1) .5 * .5 = .25
2) .25^2 = 0.0625
3) (1-.25)^2 = 0.5625
can someone let me know if I am not getting something.
thanks
