Genetic engineering applied for generating food sources is said to be different from traditional breeding. Which of the following is different in the case of genetic engineering? It always involves the mixing of different genes from similar species. It mixes genes of different organisms such as viruses and crops, spiders, and goats. It selects from the combination of genes that recombine on their own It involves the gene of the whole organism.

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.
