The average Nei's genetic distances, based on allozyme data, among populations in the Nahannian glacial lineage and the adjacent Beringian and Mississippian glacial lineages suggest that the Nahannian lineage is more closely related to the Mississippian lineage than to the Beringian lineage (Bodaly et al. 1992).
Patterns of clonal growth in natural populations of two Sagittaria species (Sagittaria trifolia and Sagittaria pygmaea) were studied based on allozyme data, and spatial autocorrelation analysis was employed to assess their clonal structures.
This interpretation was corroborated by Lavery (1992), based on allozyme data.
Gavin Naylor's 1992 study, based on allozyme sequences, upheld and further resolved this "ridge-backed" group.
Based on allozyme data, Naylor (1992) reaffirmed the integrity of this group, with the additions of the silky shark (C. falciformis) and the blue shark (Prionace glauca).
We used a phylogeny based on allozyme data [77], which has been recently confirmed using DNA evidence [78].
Estimates of mean population outcrossing rates range from 0.32 to 0.64, based on allozyme markers [74], and up to 0.94±0.27 based on morphological markers [73].
Population genetic approaches use a variety of methods including estimates of gene flow among populations based on allozyme variability, [2], [16], [17] and more recently estimates of migration using microsatellites [18], [19].
Instead, our specimens appear to belong to the S. punctatus and S. serrulatus groups, the latter of which was previously thought to have a wide distribution in North America but relatively little intraspecific variation based on allozyme analysis.
robertsoni, which was previously estimated at 3 Ma based on allozyme differences [ 33].
