a) A man whose sister was an albino (due to an autosomal recessive mutation) marries an albino girl. If the couple has a child, what is the probability that they will have normal pigmentation? (Assume that if the problem does not state that an individual is an albino that they have normal pigmentation) Hint: Make sure you take into account that the man is not an albino when you calculate your probability. b) If you find out that the second...

Normal human skin pigmentation is dominant over the albino trait. If an albino man expects a child with a woman who has normal skin pigmentation and whose father was albino, what are the possible genotypes and phenotypes of the child? Could you give a detailed solution with explannation and pedigree table? Thank you!

A man and woman are both of normal pigmentation, but both have one parent who is albino (without melanin pigmentation). Albinism is an autosomal (not sex-linked)recessive trait. What is the probability that their first female child will have albinism?
