Normal segregation of allozyme markers in complex rhododendron hybrids
Article Abstract:
A study of the inheritance of isozyme markers in Rhododendron hybrids using starch gel electrophoresis indicates that polymorphisms by nine enzyme systems are due to allelic changes at 15 loci. Disomic inheritance is regular over a wide array of genetic backgrounds in complex hybrids having an average of six species of Rhododendron for each pedigree. The absence of a considerable chromosomal differentiation and selection for chromosomal and genetic regularity over generations of breeding in Rhododendrons probably explain the low frequency of segregation distortion.

Hierarchial analysis of allozymic and morphometric variation in a montane herb, Ipomopsis aggregata (Polemoniaceae)
Article Abstract:
A study of three populations and three sub-populations of each population of Ipomopsis aggregata from three different sites shows that there is significant genetic variation in the individuals and populations. The genetic distance increases while gene flow decreases as the distance between the growing sites of the plants increases. The variance factors of allozymes increase monotonically with spatial scale while the variance in morphological factors is higher in localities than in populations.

Genetic structure of Rhododendron ferrugineum at a wide range of spatial scales
Article Abstract:
The objectives of the study were to examine the relationship between spatial and genetic distance at different geographic scales, to infer the scale at which equilibrium occurs, and to compare population structure at different angles to the slope of a mountain. The detection of such a correlation along local transects suggests the possibility of an equilibrium between gene flow and genetic drift below the scale of 2 km.
