Concept #1: Complementation

Concept #2: Non-Epistatic Genes

Concept #3: Epistatic Genes

Concept #4: Other Gene Interactions

Practice: When performing a complementation test, how do you know if two mutations complement?

Practice: How can you tell if two genes are epistatic?

Practice: Two heterozygous organisms are crossed, and the F2 phenotypic ratio is 12:3:1. What form of epistasis do these two genes exhibit?

Practice: A cross of white plants and red plants was performed. Using the F2 phenotypic ratio data below, determine what form of gene interaction is taking place. 

Practice: In the rare Bombay phenotype, a mutation in a second gene can control an individual’s what?
