#### Solution Preview

This is a probability problem where we'll use a Punnett Square to determine the possible genotypes of the offspring resulting from this cross.<br><br>The first information we are given is that albinism is an autosomal, recessive condition. Autosomal refers to any chromosome that is not a sex chromosome. Therefore, the sexes of the individuals involved in this problem do not matter. We will use "a" to represent the recessive allele and "A" to represent the dominant ...

#### Solution Summary

Punnett Square is applied. The expert examines probability of genotypes and phenotypes.
