| Abstract | Random Amplified Polymorphic DNA (RAPD) was used to reveal the variation among Seven Drosophila immigrans geographic strains. Based on the RAPD markers the genetic distance among seven geographic strains of D. immigrans were computed and a phylogenetic tree was constructed. We found that: 1) Among D. immigrans strains, MU was further away to other strains than the others for it is the only one from Japan. 2) Within Chinese geographic strains, HY, SP (from Qinling area) are collected at the nearest geographic area and height above sea level, so they have little genetic variation. Another two high elevation strains TS(from Taishan) and LZ (from Lan Zhou) went together with HY and SP. It seems that: Higher elevational D. immigrans strains have more genetic resemblance. This phenomena happened recently during D. immigrans' specialization. |
