Genes at Multiple Loci Can Determine a Single Phenotype

Genes at Multiple Loci Can Determine a Single Phenotype

A gene interaction is when genes at different loci contribute to the determination of a single phenotypic characteristic. This text provides an overview of how gene interactions are an exception to Mendelian inheritance.
