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.

In 1977, there was a severe drought on the island,
which caused many of the plants to die out. Because
the finches eat the seeds of many of these plants, the
population of birds had to compete for the seeds
that were available. Most seed-eating finches prefer to
eat the small, soft seeds (particularly during the
drought), leaving only the large, tough Tribulus
seeds for the finches not lucky enough to get to the
small seeds in time.
