1 class periods of 45 minutes each
In this activity, students will examine natural selection in a small population of wild rabbits.
Evolution, on a genetic level, is a change in the frequency of alleles in a population over a period of time. Breeders of rabbits have long been familiar with a variety of genetic traits that affect the survivability of rabbits in the wild, as well as in breeding populations. One such trait is the trait for furless rabbits (naked bunnies). This trait was first discovered in England by W.E. Castle in 1933. The furless rabbit is rarely found in the wild because the cold English winters are a definite selective force against it.
Students should understand basic Mendelian genetic terms like homozygous, heterozygous, dominant, recessive, gene, and allele. They also must understand the roll of natural selection in evolution.
