Fig. 2: Number of dispersers from assayed mixed-sex populations of 200 T. castaneum offspring from crosses within and between dispersal selection regimes.

On the X-axis, ‘H’ and ‘L’ represent the selection regime and ‘m’ and ‘f’ the sex of parents, e.g. Hm-Lf indicates that the male parent came from a high selection line and the female parent from a low selection line. Data for males and females are shown in purple and green respectively. Small filled points show experimental measures from individual crosses, while large hollow points show predictions of a GLMM fitting the effect of the interaction of sex and cross type on number of dispersers, while controlling for line ID.
