Genetics Practice 4: Pedigrees

Four two-generation pedigrees are presented in this genetics worksheet. For each, five questions are asked: Is the trait autosomal recessive, autosomal dominant, x-linked recessive, x-linked dominant, or y-linked dominant? Whenever participants answer "yes," they suggest the genotypes of the parent generation. This simple, straightforward worksheet provides valuable practice in understanding pedigrees and would make a nifty homework assignment.
