Moreover, several "agrotypes, " generated by human selection, let the breeds differ in coat color, development of horns, and docility (Ajmone-Marsan et al., 2010). Gene enrichment analysis recognized that neurobiology is affected by the loci of those genes that were over-represented and targeted by directional selection, and principle functional analyses exposed that derived single nucleotide polymorphisms in developmental genes (PAX2 and SOX2) were possible to be fixed within, or close to, regulatory sequences.

Additionally, a single gene can be involved in multiple, unrelated phenotypes (Hodgkin, 2002; Hartl, 2009), and genes of polygenic traits can act in combination to produce a single phenotype. Zhang, C., Liu, Y., Xu, D., Wen, Q., Li, X., Zhang, W., et al.
