Temporal dynamics of in vitro progressive sperm speed (PC1; left panel), and sperm head speed (PC2; right panel). Raw data are shown as red (+/t males) and grey circles (+/+ males). Lines correspond to predictions from full models (random slope LMMs) including interaction terms and centred for sperm count. Shaded areas depict approximate 95 % confidence intervals. The interaction between t haplotype genotype and incubation time was not significant for PC1 (p = 0.850) and tended to be negative for PC2 (p = 0.096; see main text and Table 2). Thus, sperm linearity and progressiveness (PC1) decreased over time for both male genotypes. In contrast, sperm head speed (PC2) tended to decrease more strongly for +/t than for +/+ males (right panel). For principal component loadings, see Additional file 1: Table S2
