PRE MENDELIAN ERA:- The process of bringing a wild species under human management is referred to as Domestication. Domestication involves natural selection and selective breeding to develop cultigens from wild plants that have higher yields, better germination and grain quality, and less toxicity Domestication genes in plants • Maize and rice domestication seem to suggest few loci of large effect are important • Sunflower domestication seems to suggest many loci of small to intermediate effect are important • 9 Domestication actively changes the genetic constitution of living organisms to satisfy the needs of farmers and consumers.
