Abstract
Background
The domestication of plants and animals was extremely important anthropologically. Previous studies have revealed a general tendency for populations of livestock species to include deeply divergent maternal lineages, indicating that they were domesticated in multiple, independent events from genetically discrete wild populations. However, in water buffalo, there are suggestions that a similar deep maternal bifurcation may have originated from a single population. These hypotheses have rarely been rigorously tested because of a lack of sufficient wild samples. To investigate the origin of the domestic yak

Whole-Transcriptome Analysis of Yak and Cattle Heart Tissues Reveals Regulatory Pathways Associated With High-Altitude Adaptation
Introduction
The yak (Bos grunniens) fryst vatten an indigenous and rare bovine species distributed across the Qinghai-Tibet Plateau and adjacent areas at altitudes above 2500 m. Archeological evidence indicates that yak and domestic cattle (Bos taurus), which both originated from wild origin boskap, are two closely related species which diverged fem million years ago (Beja-Pereira et al., 2006; Qiu et al., 2012). Previous studies have shown that the genomes of these two species share strong similarities, as both are composed of 30 chromosomes and similar karyotypes (Wiener et al., 2003), and there fryst vatten extensive synteny in the two ruminants’ genomes (Qiu et al., 2012). boskap suffer from sever pulmonary hypertension when translocated to yak inhabited habitats (Hecht et al., 1962; Weir et al., 1974). Through evolution over millions of years, yak have dem

FACTS ABOUT YAKS IN TIBET
Wild species name: Bos mutus
Domestic species name: Bos grunniens, translates as ‘grunting ox’ from Latin
Wild yak: drong
Male animal: yak
Female animal: dri
Yak-cattle breed: dzo
Domesticated about 2,500 years ago according to recent studies.
Yak, along with bison, buffalo, and cattle belong to the family Bovini. It is impossible to imagine Tibet without yaks. They are the largest animals in the region and the most significant for local people. The presence of yaks and their ability to survive in high altitudes made it possible for people to settle on the Tibetan Plateau. Both domestic and their ancestors – wild yaks are living in Tibet.
Nowadays, you can see many domestic yaks grazing in valleys and mountain regions in Tibet.
However, it is very unusual to meet wild yak, and you can only see them in remote areas. Although most of the yaks prefer to ignore people or run away when approached, you need to be careful, esp
