Research Abstract

There are two colour morphs in males of Cyprichromis fish, namely, yellow-tail morph and blue-tail morph. The aim of my study is to test the hypothesis that this dimorphism persists through disassortative mating. In the present grant, I laid the groundwork for the search for genes responsible for the male colour. Disassortative mating has received attention in the fields of evolutionary biology and physiology. This study will contribute to the progress of the areas concerned.
