Comparison of population polymorphism between Bohemia (n = 11 populations) and Moravia (n = 14

Diversity measure	Bohemia	Moravia	P

Ho	0·141	0·159	0·309

See Table 2 for definitions of the symbols used and Table 1 and Fig. 1 for population locations.

A = average number of alleles per polymorphic locus, H_o = observed heterozygosity, H_S = gene diversity, F_IS and F_ST are estimated according to Weir and Cockerham (1984).

Probability values for differences between regions are given for two-sided t-test, after 10 000 permutations. Analysis was performed with FSTAT software.
