Genomic signatures of selective pressures and introgression from archaic hominins at human innate immunity genes. One known species is even a chocolate-brown color and has dark brown eyespots. (2005). doi: 10.1093/icb/icu059, Bintanja, R., and Van De Wal, R. (2008). EMBOSS: the European molecular biology open software suite. The ornamental and sexual characteristics of peacock are distinct from other birds and are absent in closely related species such as chicken and turkey; this presents an ideal set-up to look for the genomic changes underlying the phenotypic divergence of peacock. The MYD88 protein, which is a part of Toll-like receptors (TLRs) mediated signaling, showed MSA and higher divergence from chicken in comparison to turkey among the species of the Galliformes order. Asratian, A. It is however only a case of genetic variation within the population. ,
