Mate choice for major histocompatibility complex (MHC) complementarity in the Yellow-rumped Flycatcher (Ficedula zanthopygia)

Table 2 Paired comparisons of MHC variation between within-pair and extra-pair mates

	n	Within-pair mates	Extra-pair sires	t value	p value
Male diversity	34	6.206 ± 0.197	5.852 ± 0.247	1.108	0.276
Total number of alleles	34	6.206 ± 0.197	5.852 ± 0.247	1.108	0.276
Similarity to the female	34	0.626 ± 0.023	0.529 ± 0.03	2.644	0.012*
D = 2F_ab/(F_a + F_b)	34	0.626 ± 0.023	0.529 ± 0.03	2.644	0.012*
Amino acid distance	34	0.163 ± 0.002	0.167 ± 0.002	− 2.337	0.026*

Comparisons were made between within-pair and extra-pair mates (male diversity) and between the similarity estimates for the female and each type of male (similarity to the female). *Significant with p < 0.05
