Allele-specific expression and splicing provide insight into the phenotypic differences between thin-and fat-tailed sheep breeds
The sheep(Ovis aries)was one of the first grazing animals to be domesticated approximately 11,000 years ago in the Fertile Crescent(Chessa et al.,2009).Since domestication,a wide variety of sheep breeds with different production traitsand morphological characteris-tics have been shaped under the influence of natural and artificial se-lection.According to the fat content in tail,sheep can be mainly classified into two groups:thin-and fat-tailed breeds.Fat-tailed sheep breeds comprise approximately 25％of the world sheep pop-ulation,which are known for their ability to deposit up to 20％of the carcass weight as tail fat(Yousef et al.,2012).However,the energy cost for producing fat is higher than an equivalent amount for lean tis-sue(Farahani,2010).A small size of fat is often favorable for both consumers and producers.Thus,identification of functional candi-date genes associated with tail fat deposition and meat production traits is more important in sheep breeding programs.
