Generalized linear mixed model investigating variation in female mate preferences.
| Factors | d.f. | F | P |
|---|---|---|---|
| Female group | 2, 130 | 0.450 | 0.639 |
| Stimulus group | 2, 130 | 2.108 | 0.126 |
| Male wing length | 1, 130 | 0.012 | 0.915 |
| Male tarsus length | 1, 130 | 0.227 | 0.635 |
| Male body mass | 1, 130 | 0.042 | 0.838 |
| Male badge size | 1, 130 | 0.274 | 0.601 |
| Stimulus individual heterozygosity | 1, 130 | 0.040 | 0.842 |
| Female group × Stimulus group | 4, 130 | 3.824 | 0.006 |
| Female group × Stimulus individual heterozygosity | 2, 130 | 0.121 | 0.886 |
| Female group × Male badge size | 2, 130 | 0.489 | 0.614 |
Fixed effects were female group (High, Intermediate and Low number of MHC alleles) and stimulus group (Males with High, Intermediate, Low number of alleles, and the control group). Male wing length, tarsus length, body mass, badge size and heterozygosity were entered into the model as covariates. We fitted the female individual identity as a random factor (F 1,130 = 0.031, P = 0.86) to control for the non-independence of the data. Significant F and P-values are shown in bold.
