In mice, albinism (g) is recessive to grey coat colour (G). The fur colour in mice is a single gene trait controlled by two alleles. In an ideal mouse population exhibiting Hardy–Weinberg equilibrium, a grey mouse mated with an albino mouse. Over the course of several months, 42 pups were born. If the albino allele has a frequency of 0.286, which of the following rows identifies the number of the grey and albino alleles in the population of 42 pups? Select one: a. Grey Allele Albino Allele 24 60 b. Grey Allele Albino Allele 30 12 c. Grey Allele Albino Allele 60 24 d. Grey Allele Albino Allele 12 30

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.
