albinism (the lack of melanin pigmentation) is an autosomal recessive trait. a man and woman both show normal pigmentation but both have one parent who has albinism. they have one daughter who is phenotypically normal. what is the probability that their next child would be an albino girl?



Answer :

The probability that the next child will show albinism is 0.25.

Albinism is a kind of genetic disorder that occurs in a person. This condition is caused by the lack of a pigment called melanin in a person. The lack of this certain pigment in a person's skin, hair, and eyes leads to lighter color or no color in one's skin, hair, or eyes.

In the given situation, the parents of the child are heterozygous parents.

Hence, since they both have one parent that has albinism, the probability that they will show albinism is 0.25. Since it is a recessive trait in both of them, they might or might not show it. In this case, they didn't, but the marker which carries the trait is still present in both of them. Hence, when they pass it on to their second child, the probability that the second child will show albinism is also 0.25 or 25%
