Quizplus · Accepted Answer

Pedigrees used in human genetics are family tree charts showing who has/had a particular trait. These pedigrees are used to study the inheritance pattern of genetic traits within a family. Certificates verifying a particular trait or genetic health are not used in pedigrees, and birth/death dates and photographs are not necessary for the analysis of genetic inheritance patterns.
