Heredity I: Eye Color and Tails
This simulation can be used to test the heredity of two traits; eye color and the presence of a tail. You can test one trait at a time or both at once (a dihybrid cross). Females are smaller and have darker coloring, while males are larger, have brighter coloring, and more fur.
Click on a pair to select those phenotypes for the P generation. All P generation organisms are assumed to be true-breeding (homozygous). After selecting the P generation, F1 generation data will be displayed at the top of the page. Then, click on the F1 cross at the bottom of the simulation to produce the F2. The F2 results will be displayed at the top of the simulation. In addition to F1 crosses, a backcross can be selected for the white eyes/tail x black eyes/tailless P generation crosses.
See the blog post for additional discussion of this simulation.
Worksheet and virtual lab options to accompany this simulation are available.
