Genomic analysis reveals convergent signatures of selection for milk traits in sheep and goats.

ABSTRACT:

Background

Convergent evolution offers a unique lens through which to explore the molecular underpinnings of significant phenotypic transformations. Similar selective pressures likely drove the evolution of analogous milk traits in sheep and goats. Consequently, the current study aimed to identify common selection signals for milk traits across dairy and non-dairy breeds of sheep and goats worldwide.

Results

In this study, a total of 308 whole-genome sequences from diverse sheep (n = 108) and goat (n = 200) breeds, including both dairy and non-dairy types, across the world were utilized. The population structure and genetic diversity of dairy and non-dairy sheep and goat breeds were characterized. Species-specific genes associated with milk traits, such as POU2F1, ABCD2, TRN
