Phylogeny of local sheep breeds in East Asia, focusing on the Bayanbulak sheep in China and the Sipsu sheep in Bhutan.
The phylogenetic positions of the Bayanbulak sheep in China and the Sipsu sheep in Bhutan in the northern Asian sheep group were determined on the basis of allele frequency data for five informative and polymorphic loci of blood protein and nonproteins, such as transferrin (TF), arylesterase (ES), hemoglobin-beta (HB-beta), X-protein (XP), and potassium transport (KE), using different electrophoretic and ion-densitometric techniques. Based on Nei's genetic distance, clustering analysis by the UPGMA method showed that the Bayanbulak sheep is clustered in the northern Asian sheep group. Furthermore, the Bayanbulak sheep belongs to a subgroup containing the Khalkhas and Hu sheep of the Mongolian sheep group, which is distinguished from another subgroup of the small-tailed Han, Tan, Tong, and Wadi sheep. The Bayanbulak sheep was closest to the Hu sheep, despite a morphological difference in the fat deposits. In addition to these findings, the Sipsu sheep was verified to belong to the Baruwal sheep.
