Table 3. Comparison of results obtained using DNA markers to assess patterns of genetic variation in woody species native to Mexico (M) and southern South America (SA). P% indicates percentage of polymorphic loci, a measure of the extent of genetic variation within species. (All results obtained with RAPD markers, apart from *, obtained with inter-SSR markers; values in parentheses obtained with isozyme markers). All species are trees apart from Berberidopsis, which is a woody vine. (Adapted from Premoli et al. 2007.)
