Fig. 3From: Genetic variation at MHC class II loci influences both olfactory signals and scent discrimination in ring-tailed lemursLinear relationships (black lines) between the chemical distance (relative Euclidean) and the genetic distance (number of unique MHC-DRB supertypes, i.e., MHCsupertype diff) between a-b male-male and c-d female-female ring-tailed lemur dyads during the breeding season (closed circles; a, c) and the nonbreeding seasons (open circles; b, d). The numbers of dyads are provided below each data pointBack to article page
