Abstract

We present the results of multilocus sequence comparison between the Drosophila Athabasca subspecies eastern A (EA) and west northern (WN). WN subspecies has a low overall genetic diversity than EA. There is isolation by distance within the EA race, and this isolation begins to develop between EA populations that are only about 300 kilometers apart. We did not find any significant evidence of gene flow between WN and EA when we tested the nucleotide diversity within EA and its divergence from WN across a geographical gradient, however, clinal variations in diversity within EA was suggestive of gene flow. Also, one particular EA population from Chicago indicated a relatively strong degree of introgression than all the rest of the EA populations.
