Abstract

In Australia, the sea squirt is found off the mainland and off the island of Tasmania. ·nlC extent of genetic between insular and mainland continental samples was determined by performing a DNA using PCR--RFLP on the internal transcribed spacer region of ribosomal DNA The two mainland populations were polymorphic and showed similar type frequencies, but both were significantly different from the Tasmanian population. This was also monomorphic, showing a unique type, absent from the two continental populations. The genetic differentiation could be explained by the lack flow observed between both mainland and Tasmanian populations.
