Genetics of Chicken Combs
The combs of chickens are controlled by four alleles, which interact to produce four distinct phenotypes: single, rose, pea, and walnut. In this exercise, students predict the outcomes of chicken crosses. Ideally, students should already know how to do crosses that involve two traits, the mechanisms for solving these problems are similar. My honors biology…
