A family pedigree is shown here.
A. What is the inbreeding coefficient for individual IV-2? Who is/ are her parents’ common ancestor(s)?
B. Based on the data shown in this pedigree, is individual III-4 inbred
From the pedigree shown here, answer the following questions with regard to individual VII-1.
A. Who are the common ancestors of her parents?
B. What is the inbreeding coefficient for this individual?
Consider the following pedigree below for a rare autosomal trait. Be sure to take into account the inbreeding convention, when needed.
1. What is the probability that individual B is heterozygous?
2. What is the inbreeding coefficient of individual E?
3. After divorce, individual “A” decides to marry at random outside the pedigree. If the population allele frequency of the rare autosomal trait is 0.012, what are the chances of having an affected child for his first born of his second marriage?
