Table 2.

Tajima’s D (mean of 500-bp sliding windows) for populations evolving under Full Care (FC) and No Care (NC) for each block. Statistics are presented for all windows across the genome (genome-wide) as well as for windows that overlapped with diverged genes (± 5 kb). Delta is difference between Tajima’s D between means of FC and NC populations (**p < .001).
