However, we also observed a marginally significant difference in the first principal component between the strains with different foraging index ( Kruskal–Wallis test , P = 0.0259, see supplementary fig.

2015 ) populations, we found a small, but highly significant correlation between the frequency differences of survival-lowering allele (DGRP minus DPGP) and the significant level of the SNP in GWA ( Spearman rank ρ = 0.0439, P < 10 −16 [all SNPs]; ρ = 0.0473, P < 10 −7 [SNPs P -value < 0.01]).
There are 49 protein-coding genes that have at least one SNP with significant ( P < 10 −5 ) association with our foraging index, and they show a significant trend of having higher expression in adult heads ( fig. 4 ).
