Genetic variation in Armeria maritima in Iceland
Abstract A comparison of the population genetic structure of Armeria maritima in Iceland with an earlier study in Denmark was undertaken. Ten populations were sampled in Iceland for isozyme analysis. Most populations showed Hardy-Weinberg proportions, but a higher number than statistically expected...
