The class will receive the following laboratory kits: Understanding the Human Genome, DNA Isolation, Eye Color and Polygenic Inheritance, Genetically Modified Food, a Plasmid Simulation, along with a dihybrid cross poster.
The cross described is called a "dihybrid cross," i.e., with two genes involved.
For a dihybrid cross, we ask students to predict the [F.sub.1] genetic outcomes when two homozygous pea plants with yellow round seeds and green wrinkled seeds are crossed.
* Draw a Punnett square showing a dihybrid cross, involving two traits
For example, epistatic variance comprises only 14% of [V.sub.G] with complementary gene action, i.e., 9:7 ratio in the [F.sub.2] of a dihybrid cross.
For example, in a hypothetical case, if only two loci each with two alleles are responsible for the phenotype (the actual number of loci is not known in our study), this would produce a 14:1:1 phenotypic ratio in the [F.sub.2] of a dihybrid cross and a 3:1 ratio in the backcross generations.
