Linebreeding is a ratchet mechanism for holding any gains already made by selection, while attempting to make further gains. Crossing of individuals from two species is referred to as species hybridization . hybrid Firstly, it gives companies a quantified grading of how well versed or trained an individual is for the specific role.
