Table 2 Results from randomisation testing of (dis-)assortative mating in the grey partridge based on amino acid variants of MHCIIB

From: Mate choice for major histocompatibility complex complementarity in a strictly monogamous bird, the grey partridge (Perdix perdix)

Variable 95% CI min 95% CI max Median
Amino acid variants sharing (similarity) 0.3333 0.5714 0.3333
Mean amino acid distance 0.1953 0.2215 0.2156
  1. The median for actual pairs was compared with the 95% confidence interval limits for randomly chosen pairs (based on 10 000 permutations and 36 known actual pairs)
