Abstract

The spatial variation in gene frequencies of four unlinked polymorphic loci was studied in the teleost Fundulus heteroclitus. Three loci (Idh-A, Idh-B, and Est-S) exhibit significant north-south clinal variation in allelic frequencies along the Atlantic Coast of North America, while a fourth locus (6-Pgdh-A) shows a modest clinal variation. These data, together with our previous data for Ldh-B, Mdh-A, Gpi-B, and Pgm-A, reveal a pattern of low gene diversity in the colder northern extremes of the species range and high gene diversity in warmer southern latitudes.
