Fig. 5: Selected genes were identified in three durian populations.

A–C Joint distribution plots of Fst and ROD for pairwise comparisons among populations: A POP1 vs. POP2, B POP1 vs. POP3, and C POP2 vs. POP3. Each dot represents a 100-kb genomic window. Red dots indicate windows within the top 5% of both Fst and ROD values, considered candidate regions under positive selection. Marginal histograms show the distribution of Fst and ROD for each comparison. Blue dashed lines represent the 95th percentile cutoffs for each metric. D The number of overlapping and unique candidate genes under selection among the three population comparisons.
