Figure 2 Ward dendrogram of
Dracocephalum thymiflorum
populations. (Populations 1-5 are according to Table 1).
population genetic variation have been used to prioritize
for conservation efforts (Petit et al
.
,1998) with, all else
being equal, more weight given to those populations
exhibiting higher levels of within-population variation,
and to those that are more genetically divergent from
others. In our study the population 2 was genetically
differentiated from the other studied populations and
also contained a high degree of within population
genetic variability.
These populations may have increased likelihood of
persistence over less variable population and hence the
ability of a population to contribute demographically to
the species through time, and have increased adaptability
in the face of future environmental change.
The STRUCTURE plot and population assignment
revealed some degree of genetic admixture among the
studied
Dracocephalum thymiflorum
populations.
Therefore, in spite of population differentiation, limited
gene flow occurred among these populations.
