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.

a. Summarise the data on morph frequencies, allele frequencies and index of
polymorphism for the three populations in a table.
b. Summarise in a table the estimates of genetic differentiation (FsT) between the
populations for both shell colour and banding alleles. Note that you do not need to
aenerate bar charts for each of the populations.
c. With reference to all the information given in Table 1 and summarised in your tables in
(a) and (b), explain how each of these samples differs from the others, and which of the
samples are most genetically similar to each other. It should be clear from your answer
on what evidence your conclusions are based and your answer should be no more than
200 words in length (mandatory word limit).
d. Outline two possible reasons for the differences you have observed and explain why
these reasons might account for the differences. Your answer should be no more than
200 words (mandatory word limit).
