title: Population genetics of a "colonising" lizard: natural selection for allozyme morphs in Anolis grahami.
abstract: Allozyme frequencies of Anolis grahami from Bermuda were compared to those from Jamaica. These lizards were introduced into Bermuda from Jamaica in 1905. The magnitude of the genetic changes were consistent with the hypothesis that these changes were produced by random genetic drift. The changes for the seperate alleles were, however, more heterogeneous than expected if caused by random drift alone. It is concluded that not all the alleles examined have been selectively neutral.
