What are three ways that pedigrees are beneficial?

By analyzing a pedigree, we can determine genotypes, identify phenotypes, and predict how a trait will be passed on in the future. The information from a pedigree makes it possible to determine how certain alleles are inherited: whether they are dominant, recessive, autosomal, or sex-linked.

Explanation:

Pedigrees are family trees which show the parents and offspring across generations, as well as who possessed particular traits. Pedigrees of individual families are used by genetic counselors, to aid them in providing information to families who may be at risk for various genetic conditions.
