In this article, we are, however, focusing on a classical meaning of genetic interaction that a genotypic effect at a gene is influenced by another genotype at another gene on the same genome (Falconer and Mackay, 1996).
Utilizing this lethal genetic interaction as a phenotyping tool, they analyzed 2,250 mouse offspring, corresponding to approximately half genome coverage, and identified 15 mice that survived to weaning.

Objective: The aim of this project is to use the ninespine stickleback as a model to understand the relative importance of natural selection and random demographic events in shaping the evolution of ecologically relevant complex traits; harness the demographic history of the stickleback to detect complex genetic interactions affecting complex traits; improve the empirical understanding of the genetics of complex traits, and explore the effect of copy number variation (CNV) on complex traits.
