Table 3. Linear model analyses of variance for clutch mass and egg size (residuals of egg size against clutch mass) on (a) female leg length and population origin, (b) female condition (that is, residuals of body mass against leg length log–log regression) and population origin, (c) female leg length, condition and population origin, (d) MLH and female leg length and (e) MLH, female leg length and population origin.

Nonsignificant MLH × population interaction has been removed of the final models. Estimates and standard errors are presented in the Appendix (Supplementary Table S4).Bold values indicate significant effects.
