A Punnett Square: A tool to help manage simple genetic traits

Written and prepared by Dr. Jackie Atkins, Director of Science and Education A Punnett squares is a handy tool to predict expected progeny outcomes from a specific mating.  A Punnett square only works with simply inherited traits (where one or just a few genes control the phenotype i.e., coat color, horned/polled, or many genetic conditions).…
