Day 23: Pedigrees

We learned how to analyze the pedigrees of generations to discover whether a condition is sex-linked or autosomal.

This is an example of a pedigree they use roman numerals on the side for each generation and numbers left to right. This pedigree is autosomal because the number affected is not higher than 50% in offspring of the a certain sex. It is also recessive because none of the II offspring showed this trait.
