Why would a pedigree be useful to a doctor or genetic counselor?

How are pedigrees used by genetic counselors? Genetic counselors use pedigrees like the one above to figure out how certain conditions are being passed down through a family and which family members, who may seem healthy now, could be at risk of already having that condition or developing it later.

How can a pedigree be a useful tool for geneticists?

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.

Why are pedigrees used?

A pedigree shows relationships between family members and indicates which individuals have certain genetic pathogenic variants, traits, and diseases within a family as well as vital status. A pedigree can be used to determine disease inheritance patterns within a family.

Why is a pedigree chart important to a geneticist breeder?
