Already in the “On the Origin of Species” 1859 and later in the “The Variation of Animals and Plants under Domestication” 1868, Charles Darwin diagnosed that an identical processes of alternative that act in nature also apply to selective breeding where they’re sped up orders of significance by breeders’ goals to obtain particular traits. Obviously, Darwin couldn’t know the genomic basis that underlies the chose traits. This started to change, especially in the last decade, as genome sequences may be received for more species. Yet, we are still only in the beginning of knowing how the genotype controls and determines the phenotype Frazer et al. 2009.
