Table II

Number of alleles, expected heterozygosity He, and inbreeding coefficient FIS within each population of Bombus terrestris diploid workers representing individual colonies in sites A and B as well as genetic differentiation FST between the populations at 12 microsatellite loci and over these loci. Asterisks show significant differences (P < 0.05) from zero, and “ns” shows that the difference is not significant.
