1

Akaike information criterion values given as the difference from the best model.

2

Residual deviance is a measure of the goodness-of-fit of a model to the data. Higher values indicate that more variation is unaccounted for by the model and, therefore, lower values indicate models with a better fit.

3

Degrees of freedom of the residual deviance.

4

Insignificant residual deviance (P > 0.05) means the residual variance is adequately explained as sampling error and, therefore, the model is an adequate description of the data. Insignificant residual P-values are given in bold.

Results for all nine possible asymmetrical models are given (except for P. metcalfi / P. teyahalee heterozygotes because none were found at the nuclear marker). Each asymmetrical model was constructed by adding interaction terms involving the listed marker genotype and all relevant genotypic categories. Genotypes with ‘ / ’ are diploid ILF3 genotypes and all others are mtDNA genotypes.
