In mice and man, females prefer males with a major
histocompatibility complex (MHC) genotype different
to their own. We tested whether this phenomenon
also occurs in the Swedish sand lizard (Lacerta
agilis). Females in a laboratory experiment preferred
to associate with odour samples obtained
from more distantly related males at the MHC class
1 loci. Data on free-ranging lizards suggest that
associations between males and females are nonrandom
with respect to MHC genotype. However,
male spatial distribution and mobility during the
mating season suggest that the non-random pairing
process in the wild may also be driven by corresponding
genetic benefits to males pairing with less
related females.
