Genetics Practice – Roan Cows with Horns
Practice genetics with cows! Cows can be horned (hh) or hornless. They can also be red, white, or roan colored.

Multiple Allele Traits in Rabbit Coat Color
Students practice genetics of multiple allele traits as they study coat colors in rabbits: black, chinchilla, Himalayan, white.

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…

Modeling Independent Assortment & Dihybrid Crosses
Students examine how two traits are inherited, revealing that each allele has an equal chance of being passed on to the next generation, the principle of independent assortment.

What is a Map Unit Anyway?
Chromosome maps illustrate how far alleles are on a chromosome using a MAP UNIT. Map units are based on the frequency of cross-over
