Which scenario would most likely result in genetic drift? When predators are removed from an island, the island's population of finches grows larger. Climate change causes the arctic habitat of a population of ringed seals to become gradually warmer. Several individuals in a population of wolves are killed by ranchers when they attack a herd of cattle. A population of moose living at the base of a volcano is nearly wiped out when the volcano erupts.
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.
