Abstract: | Morphometric and isoenzymatic data have showed little variation among Drosophila antonietae populations. This suggests historic gene flow, due to the distribution of these populations, which are associated with cacti along rivers, and natural selection on these markers. Microsatellite loci have high variability and are ideal for detecting gene flow and analysing population structure. Here we describe the isolation of seven polymorphic microsatellite loci in D. antonietae. |
