Identification methods for high-altitude adaptation of phenotypes in ruminant livestock: status and prospect
Year: 2023
Type: article
Abstract: Adaptive traits refer to the developmental patterns evolved in organisms to cope with a specific environment. At high altitudes, oxygen is the most important environmental factor affecting the survival of organisms. The long-term evolutionary history shows that organisms (e.g., yak) have developed distinct phenotypes in high-altitude environments. Moreover, domestic ruminants, such as sheep, goats, and cattle, have played an essential role in providing permanent occupation to humans living in high-altitude regions and have also adapted to the high-altitude environment in a short period (~3000–5000 years). This review summarizes the high-altitude adaptation of phenotypes in ruminant livestock and the identification methods for each trait and compares the traditional and modern high-throughput identification methods. This review will outline future studies on accurate and high-throughput identification methods for high-altitude adaptation of phenotypes, thereby guiding researchers in adaptation evolution and breeding.
