Fig. 3From: Within-species divergence in the seminal fluid proteome and its effect on male and female reproduction in a beetleScree plot from a principal component analysis of 127 seminal fluid proteins. Given are the proportion of total variance in SFPs explained by successive PCs (filled circles) and F-values (open circles) from ANOVAs testing whether populations differ along each PC. Dashed line represents the critical F - value for P = 0.05Back to article page
