Between a pedigrees showing autosomal recessive inheritance versus one shows autosomal dominant inheritance.

Introduction:

A pedigree is a chart of a family’s history with regard to a particular genetic trait. In a pedigree, males are designated by squares and females by circles. Shaded circles and squares represent individuals expressing the genetic which are often a disorder. A line between a square and a circle represents a union. A vertical line going downward leads directly to a single child. Generations are numbered down the left side, and individuals are then identified from left to right.
