Table 1 The observed and estimated numbers of S-alleles (by the ML method of Paxman (1963) and the E2 estimator of O’Donnell and Lawrence (1984)), 95% CI for the ML estimation, repeatability statistic R, MA and P-value of the isoplethy test for each M. sieversii population, and the combined populations for each of M. sieversii and M. sylvestris

  2. Individuals with unidentified S-alleles were excluded from the analysis.
  3. aThe allele number and repeatability statistic for M. sylvestris were estimated using the S-allele data from Table 2 in Dreesen et al. (2010).
