Abstract
The genetic polymorphism of a population of Pinus halepensis was studied using 12 electrophoretically detectable enzyme systems encoded by 7 monomorphic and 10 polymorphic loci. An estimation of population parameters revealed a relatively high average heterozygosity (H=0.179). The total variation present in the population was partitioned into a high amount of genetic variation within groups, with only 1.3–4.4% of the total variation resulting from genic differences among groups.
