Additive value

Term Definition
Additive value
Additive value in genetics refers to breeding value for traits that are controlled by multiple genes (polygenic), each gene adding or reducing to the genetic potential for that trait for that animal. An example of this is growth, where several genes are involved in an animal's genetic ability to grow faster and the combination of these genes will represent the animal's growth. These are important to animal breeders as these are the genetic component that we select for with EPDs.
