The gray mouse lemur (Microcebus murinus) is a species in which females come into estrus and mate with several males on one night each year. Females accept any and all partners, but a genetic analysis of offspring indicated a greater difference in the MHC genes of mothers and actual fathers than in mothers and males selected at random from the population (Schwensow et al. 2008). Use these results to evaluate the various hypotheses on the indirect genetic benefits of polyandry. What do they suggest about the mechanism that enables a sexually promiscuous female mammal to exercise mate choice? Don't write from any online source..
Genetic Variation
Genetic variation refers to the variation in the genome sequences between individual organisms of a species. Individual differences or population differences can both be referred to as genetic variations. It is primarily caused by mutation, but other factors such as genetic drift and sexual reproduction also play a major role.
Quantitative Genetics
Quantitative genetics is the part of genetics that deals with the continuous trait, where the expression of various genes influences the phenotypes. Thus genes are expressed together to produce a trait with continuous variability. This is unlike the classical traits or qualitative traits, where each trait is controlled by the expression of a single or very few genes to produce a discontinuous variation.
