| the genetic structure of drosophila ananassae populations from asia, australia and samoa. | information about genetic structure and historical demography of natural populations is central to understanding how natural selection changes genomes. drosophila ananassae is a widespread species occurring in geographically isolated or partially isolated populations and provides a unique opportunity to investigate population structure and molecular variation. we assayed microsatellite repeat-length variation among 13 populations of d. ananassae to assess the level of structure among the populat ... | 2007 | 17237518 |
