Post by knanyes » Thu Feb 07, 2008 2:17 am

pedigree is a chart that shows how a trait is inherited through a family.[/color]
circles: females
squares: males
shaded: individual is affected with the trait
carrier: an individual that carriers the allele for a trait but does not express the trait.

steps to completing a pedigree

1: place two lower case letters by every affected individual
2: place one upper case letter case next to every normal individual.
3: use the pedigree to determine the genotypes of the normal individuals.
