Genetic variation at MHC class II loci influences both olfactory signals and scent discrimination in ring-tailed lemurs

Table 2 Partial Mantel tests showing the seasonal relationships between the relative Euclidian chemical distance (for genital odorants) and MHC-based genetic distance for same-sex (MM and FF) dyads of ring-tailed lemurs

Chemical distance is based on 203 and 338 compounds for MM and FF dyads, respectively. Tests include three socio-demographic and environmental variables as covariates. Sums of squares (SS) and partial Mantel correlation coefficients (r) with significant P values (P ≤ 0.05) are shown in bold type, whereas trending values (P ≤ 0.10) are shown in italics
