P. Seppa et P. Gertsch, GENETIC RELATEDNESS IN THE ANT CAMPONOTUS-HERCULEANUS - A COMPARISON OF ESTIMATES FROM ALLOZYME AND DNA MICROSATELLITE MARKERS, Insectes sociaux, 43(3), 1996, pp. 235-246
Genetic structure of Camponotus herculeanus populations was studied us
ing both traditional allozyme markers and recently discovered DNA micr
osatellites. Relatedness among worker nest mates was high in one study
population (0.70), but lower in another (0.48). The estimates lower t
han 0.75, together with the multilocus genotype patterns, indicate eit
her multiple mating by queens, or multiple queens reproducing in the c
olonies. These two could not be distinguished with the current data, a
lthough multiple matings seem a more probable explanation for the rela
tedness estimates bearing social biology of the species in mind. Inbre
eding coefficients suggested random mating in both populations. Both a
llozyme and DNA microsatellite markers gave the same result concerning
genetic parameters estimated, but the higher variability of the micro
satellites resulted in more precise estimates of both parameters.
