As you may recall, pedigrees are charts of family histories that show the phenotypes and family relationships of the individuals. Doctors and scientists have used pedigrees to study human genetics long before the technology existed to sequence DNA. The concept is actually pretty simple. A family history is taken and a family tree is constructed.
Pedigrees are used to help detect many different genetic diseases. A pedigree can also be used to help determine the chances for a parent to produce an offspring with a specific trait. Four different traits can be identified by pedigree chart analysis: autosomal dominant, autosomal recessive, x-linked, or y-linked. Partial penetrance can be shown and calculated from pedigrees. Penetrance is the percentage expressed frequency with which individuals of a given genotype manifest at least some degree of a specific mutant phenotype associated with a trait.
