Using grey squirrels as an example, describe a population that would be of interest to a researcher. How would your approach to squirrels differ if you were going to measure tail length on a sample vs doing a census? Using white tailed deer as an example, describe a population that would be of interest to a researcher in Central Illinois. What variable might be of interest?
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.

The main type of squirrel that is found in North America is gray squirrels. A population of interest would be a grey squirrel population that includes individuals from various age brackets and sizes, including both males and females.
