Abstract
Comparative population genomics and genome-wide association studies (GWAS) offer opportunities to discover human-driven detectable signatures within the genome. From the point of view of evolutionary biology, the identification of genes associated with the domestication of traits is of interest for the elucidation of the selection of these traits. To this end, an F2 population of ducks, consisting of 275 ducks, was genotyped using a whole genome re-sequence containing 12.6 Mb single nucleotide polymorphisms (SNPs) and four plumage colors. GWAS was used to identify the candidate and potential SNPs of four plumage colors in ducks (white, spot, grey, and black plumage). In addition, FST and genetic diversity (π ratio) were used to screen signals of the selective sweep, which relate to the four plumage colors. Major genomic regions associated with white, spotted, and black feathers overlapped with their candidate selection regions, whereas no such overlap was observed with grey plumage. In addition, MITF and EDNRB2 are functional candidate genes that contribute to white and black plumage due to their indirect involvement in the melanogenesis pathway. This study provides new insights into the genetic factors that may influence the diversity of plumage color.

Abstract
Among registered Indian buffalo breeds, Nili Ravi is well known for its production potential as well as unique typical five white markings, because of which it is also known as Panch-Kalyani. In this study an attempt was made to understand the inheritance pattern of white markings in 720 progenies sired by 21 bulls and belonging to 381 dams at an organized farm. Based on extent of white markings, animals were classified into typical, under and over white categories and significance of inheritance was tested by Chi- Square, Likelihood ratio and Mc-NemarBowker tests to confirm the results. The results showed distribution of inheritance pattern from sire to progeny, and dam to progeny was that the identical in white markings classes ratios and inheritance of skin/coat colour patterns could not be explained. Further, studies at genomic and epigenetic levels needed to reveal the genetic/methylation differentiation basis of white markings variation in Nili Ravi buffalo.
