Bernard Omolo has authored a paper entitled “Cautions of using Allele-based Tests under Heterosis,” which is to appear in the forthcoming issue of the International Journal of Statistics in Medical Research. The paper discusses the influence of heterosis on the power of allelic tests, which has largely been ignored in genetic association studies, and recommends  an assessment of the existence of heterosis during model selection in order to minimize false negative genetic associations. Omolo is an associate professor of mathematics.
