A human male and female couple with brown eyes discoverthat, in both their families, their fathers (with brown eyes) eachhad siblings with blue eyes. In this example, blue eyes is anautosomal recessive disorder. None of their grandparents had blueeyes. Assume that the blue eyes in both families were caused bymutations in the same gene, and that there were no new mutationswithin the pedigrees. Mothers are not carriers of mutations in theblue eye gene.

1.) what is probability that the male in the couple is acarrier of the blue eye disease gene?

2.) If the couple had one child, what would be the overallprobability that child would have blue eyes?
