1. Which best describes the mode of inheritance of the afflicting allele in the following pedigree? A. autosomal dominant B. autosomal recessive C. X-linked dominant D. X-linked recessive 2. Suppose that an allele, b, of a X-linked gene is recessive and lethal (if a wild-type allele is not present). A man marries a woman who is heterozygous for this gene. If this couple had a large number of normal children, what would be the predicted sex ratio of these children (ratio of male children to female children)?
