Selective breeding could be unintentional, for example, ensuing from the process of human cultivation; and it might additionally produce unintended – desirable or undesirable – outcomes.

Most likely, there has been an interdependence between natural and synthetic elements that have resulted in plant domestication. The pure breeding season of the horse is from May until August.
Documentation of the genetic adjustments was considered necessary as they help in nice tuning further choice schemes. Selective breeding in aquaculture holds excessive potential for the genetic improvement of fish and shellfish.
