Y chromosomal haplotype characteristics of domestic sheep (Ovis aries) in China
چکیده انگلیسی


• One novel size fragment in SRYM18 region was found in Chinese sheep firstly.
• Two novel male haplotypes was observed in Chinese sheep firstly.
• The paternal gene flows probably affect the development of sheep breeds in China.

Investigations on the variation present at the male-specific Y chromosome region provide strong information to understand the origin and evolution of domestic sheep. One SNP OY1 (g.88A > G) in the upstream region of SRY gene, and the microsatellite SRYM18 locus within ovine Y chromosome were analyzed in one hundred and forty five samples collected from eleven breeds in China. SNP OY1 was analyzed using PCR-SSCP method and sequencing. Two different PCR-SSCP patterns represented two specific sequences with sequence analysis revealing SNP-OY1 (g.88A > G) were observed, while SNP A-OY1 showed the most common frequency (82.8%). Sequencing of the SRYM18 region revealed one novel size fragment (A2) with different repetitive units. Seven haplotypes (H4, H5, H6, H7, H8, H9 and H12) and two novel haplotypes (Ha and Hb) were established using combined genotype analysis. H6 showed the highest frequency (43.4%) across all breeds, and H8 showed the second frequency (24.1%). Ha was only found in one breed (Tan), while Hb was present in three breeds (Gansu alpine, White Suffolk and Duolang). Our findings reveal one novel allele in SRYM18 region and two novel male haplotypes of domestic sheep in China.
