Genetic variation in Arabis petraea, a disjunct species in northern Europe
Variation at 7 isoenzyme loci was studied m 15 populations (6 from Iceland, 4 from W Norway, 4 from central Sweden at the Bothnian Gulf, and 1 from Russian Karelia) Heterozygosity within populations was found to be remarkably high compared with taxa with similar reproductive systems and phytogeograp...

| Summary: | Variation at 7 isoenzyme loci was studied m 15 populations (6 from Iceland, 4 from W Norway, 4 from central Sweden at the Bothnian Gulf, and 1 from Russian Karelia) Heterozygosity within populations was found to be remarkably high compared with taxa with similar reproductive systems and phytogeographical histories Genetic distances calculated from isoenzyme data showed a close connection between the Norwegian and Swedish populations, indicating a western rather than an eastern immigration route for the isolated Swedish population Leaf shape variation displayed a large scale geographical pattern with strong differences between regions and low variation within populations |
