By comparing allozyme and RFLP loci in samples from similar geographic regions, however, one eliminates the confounding effects of unknown population relationships. The L-K test statistic is highly significant (x2 = 24.6, d.f. = 5, P < 0.001), indicating that as a group the 10 allozyme loci are more homogeneous than expected from the variation exhib- ited by the RFLP loci. Removal of the most variable RFLP locus (GM798) does not alter this conclusion (x2 = 13.1, d.f. = 5, P= 0.023).
