Associaton of MC1R variaton and plumage color diversity of Nigerian domestc pigeon (Columba livia domestca)

Objectves: Domestc pigeons (Columba livia domestca) have diverse plumage pigmentatons. Melanocortn 1 receptor (MC1R) gene variaton has been correlated with color traits. The associaton between MC1R and plumage coloraton in African domestc pigeons is yet to be investgated. Materials and Methods: Here...

Description
Summary:	Objectves: Domestc pigeons (Columba livia domestca) have diverse plumage pigmentatons. Melanocortn 1 receptor (MC1R) gene variaton has been correlated with color traits. The associaton between MC1R and plumage coloraton in African domestc pigeons is yet to be investgated. Materials and Methods: Herein, we report the relatonships between single nucleotde polymorphisms (SNPs) in MC1R and plumage of 35 domestc pigeons from Nigeria with 4 diferent plumage phenotypes plus 37 published MC1R sequences from France (n = 14) and Russia (n = 11). Results: We obtained 14 SNP sites among 72 individuals. Missense mutatons C206T (Ser69Leu) and G253A (Val85Met) were observed in 16 and 8 Nigerian pigeons, respectvely. The chi-squared test (p < 0.05) for C206T, G253A, and A520G has the advantage of homozygous genotypes CC, GG, and AA, respectvely. The associaton of C206T loci showed the advantage of CC genotype in ash-red, spread, and white pigeons, and TT in blue-bar, spread, and white feather pigeons. For G253A and A520G loci, GG and AA were dominant in all plumages except for genotype AA in G253A, which was prominent in ash-red, spread, and white plumages. The three SNPs were assigned to seven haplotypes. The median-joining network revealed 20 haplotypes, including 5 in Nigeria and 2 shared. Conclusion: This study provides an insight into the associaton of MC1R variaton and plumage diversity in Nigerian domestc pigeons. However, due to the limitaton of the current data, we could not make further conclusions; this necessitates the need for more genomics studies on Nigerian pigeons.
