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.
What is an area of genetics that analyzes differences among individuals?
Introduction
In the population there is a great variation present in the genetic information of any individual. No two individuals can have same genetic material in the population. Theis genetic diversity can be attributed to the polymorphism of DNA.
Polymorphism is referred as the presence of different alleles for the same gene in the population. Even the monozygotic twins also have genetic variation which occurred during the developmental phase.
Alleles can occur at different frequencies in the human population, and the frequency of variation would be higher in the remote population which is not in proximity to other human population.
