Pedigree analysis is an approach to studying human genetics where an inherited trait is analyzed over the course of a few generations. Geneticists make use of a pedigree, or famdy tree, to understand how simple human traits are inherited - whether the mutant allele is dominant or recessive, autosomal or sex-linked Shown below are three pedigrees. Match each pedigree with its corresponding form of inheritance. (Circles represent females, squares represent males, open shapes indicate the individual does not have the condition being studied, filled shapes indicate the individual has the condition).
