The admixture event consisted of a source population that was 35% African and 65% East Asian.
Plants in a garden or maintained landscape often form a source population from which plants can colonize new areas.
However, the mean of the frequencies across all lines from the one source will be the same as the original frequencies in the source population.
They determined that these lions are genetically unique and presumably that "their wild source population is similarly unique."
An additional advantage of using automated data from health plans is the ability to know the exact size, composition, and residence location of the source population.
Both the existence of the source populations and the mechanisms that maintain the collision rate depend on how worlds are distributed.
Local populations depend on immigration from source populations in the south, mainly in Iran.
Wherever these areas were found, they became a source populations during interglacial periods.
Local patches of dense cover could serve as source populations or reservoirs to colonize less favorable habitats with sparse cover.
Thus Engset's equation should be used when the source population is small (say less than 200 users, extensions or customers).
