The correct option is A Best feeding habits and management facilities can cause cause performance way beyond their genetic limit
Controlled breeding refers to the scientific process of mating selected individuals to produce offspring with desirable characteristics. There are a lot of factors considered while choosing animals to be bred. Most important is their genotype. The produce or yield is a direct function of their genetic makeup. Feed and management do increase their yield but not beyond their genetic limit. If a cow is low milk producing genetically, giving double the feed will not lead to production of milk as much as a high milk producing cow. Heritability of traits in progenies is essential so that desired characteristics are passed down successfully to the progeny. Some animals release single or some may release many ova during ovulation, but at least one of them should be functional for successful fertilisation. Before breeding, their reproductive organs, semen quality, testes, etc should be checked.
