Observed heterozygosity ( H
between females and males at 14 Ppsm loci in nine-spined sticklebacks. A and D, HO in females (white) and males (gray); B and E, FIS in females (white) and males (gray); C and F, FST between females and males. A-C, Baltic Sea; D-F, Pyöreälampi. *P < 0.05, **P < 0.01 and ***P < 0.001. The blue colour indicates the loci where significant FST was observed. Physical locations of loci were determined based on the three-spined stickleback genome.
