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.

potentially improve food quality.
Genetic engineering is also known as genetic modification or manipulation. It is a process by which the genes or genome of an organism is directly manipulated by using the biotechnology. It is a set of techniques which are used to modify the genetic makeup of the cells. It also includes transfer of genes within the species or across the species to produce new and improved varieties of organisms.
