The Gayal (Bos ontalis) is a domtited bove speci that is native to Southeast Asia. It is also known as mhun or gayal, and is closely related to * the gayal animal *
To vtigate the phylogenic posn of gayal, we retrieved nucleoti and prote data for ttle (Bos ts) [19], yak (Bos gnniens) [17], wisent (Bison bonas) [20], bison (Bison bison) [21], zebu (Bos dic) [22], and buffalo (Bubal bubalis) [23] om the NCBI database.
Addnally, we sequenced the plete mochondrial DNA (mtDNA, the first plete mtDNA of the gayal submted to GenBank: MF614103) g the Sanger sequencg method, due to the fact that next-generatn sequencg methods have lower abily and accuracy reverg repeat sequenc [28, 52], particularly regns wh rich GC ntent like the D-loop.

Here, we performed whole-genome sequencg of one Gayal for the first time, wh one Red Ang ttle and one Japane Black ttle as ntrols. In total, 97.8 Gb of sequencg reads were generated wh an average 11.78-fold pth and >98.44% verage of the reference sequence (UMD3.1). Numero different variatns were intified, 62.24% of the total sgle nucleoti polymorphisms (SNPs) tected Gayal were novel and 16,901 breed-specific nonsynonymo SNPs (BS-nsSNPs) that might be associated wh tras of tert Gayal were further vtigated. Moreover, the mographic history of bove speci was first analyzed and two populatn expansns and two populatn bottlenecks were intified. The obv differenc among their populatn siz supported that Gayal was not B. ts. The phylogenic analysis suggted that Gayal was a hybrid scendant om crossg of male wild gr and female domtic ttle.
