Inbreeding coefficients ( ), observed and expected heterozygosity ( / ) of population Cl and Dp, genetic differentiation ( ) between Cl and Dp, and number of alleles ( ) for Cl and Dp. None of the values was significantly different from zero. Significant deficits of heterozygotes from Hardy-Weinberg equilibrium are given in bold. Note: small negative values are statistical artefacts and are observed in populations with very low genetic differentiation.
