Question

what is pedigree used for ?

Answer 1

Many things, but at its core it simply is a history of familial relationships, such as all offspring from person A. Can you think of how this would be useful when looking at genetic diseases?

Answer 2

Analysis of the pedigree using the principles of Mendelian inheritance can determine whether a trait has a dominant or recessive pattern of inheritance. Pedigrees are often constructed after a family member afflicted with a genetic disorder has been identified
