Marker-assisted breeding is a conventional technique that allows breeders to track genes without using transgenic approaches. It can be used in plants and animals to select qualities that are desirable for farmers and consumers. Marker-assisted breeding doesn't produce genetically modified organisms.
Marker-assisted breeding uses DNA markers associated with desirable traits to select a plant or animal for inclusion in a breeding program early in their development.
This approach dramatically reduces the time required to identify varieties or breeds which express the desired trait in a breeding program. The marker is not the gene for the trait, but a genetic marker which is usually inherited with the trait. Desirable traits include characteristics such as disease resistance, size and high yield.
