Genomic analysis reveals population structure and selection signatures in plateau dairy cattle.

ABSTRACT:

Background

To solve the problem of an insufficient supply of dairy products in Tibet, work has been carried out to improve native dairy cattle and introduce purebred dairy cattle from low-altitude areas. The harsh environment of the plateau not only severely limits the production performance of high-yielding dairy cattle, such as Holstein and Jersey cattle, but also challenges their survival. The population structure and plateau adaptation mechanism of plateau dairy cattle are rarely reported. In this study, key genes and pathways affecting plateau purebred and crossbred dairy cattle were explored using genetic chip information.

Results

The results showed that the genetic diversity of the Tibet dairy cattle population was higher than that of the native cattle and plains dair
