Answer:
Molecular genetics is the manipulation of an organism's genome. There have been many uses of MG outside the farm gate for generating customised bacterial cultures. When MG is used in dairy animals, it results in transgenic animals with new traits that can't be achieved through standard breeding techniques. Inside the farm gate, MG plays a role in animal breeding. Causative mutations or linked genetic markers that cause phenotypic differences are being identified using MG. This approach aims to disseminate superior genetics to commercial farmers effectively and efficiently.
