n a population of rabbits, half of the rabbits are brown and half are grey. Because male and female rabbits prefer to mate with only brown rabbits, eventually the population ends up with about 90% of the rabbits being brown. We can say that:   grey rabbits will go extinct soon. no evolution has occurred because the change in allele frequencies is due to mating preference. evolution by non-random mating (or sexual selection) has occurred. evolution by natural selection has occurred.

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.
