The genetics laboratory is divided into two distinct experiments covering Mendelian genetics and Population genetics. For Mendelian experiments, students can select a set of traits for the selected species, define the initial genotype for the parents, and cross these parents to produce the first generation of offspring. For the first generation, specific or random crosses of the offspring can then be performed to produce subsequent generations. For each generation a summary is provided showing the frequencies of each of the phenotypes, and students can also view the phenotypes of each of the individual offspring. The goal is to allow students to observe how the selected traits get expressed as a function of generation, and then from these observations determine and understand the genetic model governing expression of these traits.


In a Population experiment, students will be able to select an allele frequency within a population and manipulate different forces on that population to see how they affect the Hardy-Weinberg equilibrium. These forces and variables include population size, allele frequency, mutation rates, genotype fitness, assortative and disassortative mating, and linkage disequilibrium. The goal is to demonstrate the basic principles of Hardy-Weinberg equilibrium and also the effects of population forces on this equilibrium.
