Genomic regions with selection signatures in Xinjiang Mongolian cattle. Genome-wide distribution of the π ratio (A), FST (B) and XP-EHH (C). The red line represents the threshold value for the top 1% based on three metrics: the π ratio (1.61), FST (0.11), and XP-EHH (2.13). D Functional annotation of several candidate selected genes responsible for the adaptation to desert environment. The names of the KEGG pathways, GO terms, or other functions are shown in green. The candidate genes positively selected are shown in black. The potential mechanisms behind the adaptation to desert environment are shown in blue. Four genes belonging to the cytochrome P450 family 2, subfamily J are implicated in various functions
