Albinism, lack of pigmentation in humans, is an autosomal recessive disorder. A normally pigmented woman who has an albino uncle wishes to marry a phenotypically normal man whose sister is an albino. (Assume that these are the only individuals known to be albino in the two families) What is the probability that the couple's first child is an albino girl

Hi, you've asked an incomplete question. The missing options read;

a. 1/6

b. 1/9

c. 1/18

d. 1/36

e. none of these choices

Answer:

e. none of these choices

Explanation:

Remember, someone with an h.o.m.o.z.y.g.o.u.s gene basically inherits two identical alleles; one from their biological mother and the other their biological father.

In this scenario, the real concern should be to determine the probability that the girl child inherits a dominant allele that contains the gene that causes albinism. Hence, since there's little information about the gene type of the parents, a concise assumption can be made, thus rendering the listed options unlikely.
