In agriculture and animal husbandry, the Green Revolution’s use of traditional hybridization increased yields with the aid of breeding “high-yielding types”. The replacement of regionally indigenous breeds, compounded with unintended cross-pollination and crossbreeding (genetic blending), has decreased the gene pools of various wild and indigenous breeds ensuing inside the loss of genetic range. Since the indigenous breeds are often nicely-tailored to local extremes in weather and have immunity to nearby pathogens, this may be a large genetic erosion of the gene pool for destiny breeding. Therefore, business plant geneticists attempt to breed “extensively adapted” cultivars to counteract this tendency.
