Imagine two populations of fish who are part of the same species. Though they are the same species, the two populations live in slightly different habitats and have some differences in their genetic code because of this. Imagine that several fish from population A migrate to the population B and reproduce. This introduced additional genetic variation to population. This is an example of: Group of answer choices Mutation Gene flow Genetic drift Natural selection
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.
