Starch gel electrophoresis has shown that natural populations of Fundulus heteroclitus have electrophoretic variants for at least 21 loci. We provide inheritance data for 10 polymorphic systems: esterases (Est-B, EST-C, and Est-D); aspartate amlnotransferases (Aat-A, and Aat-B); mannosephosphate isomerase (Mpl-A); acid phosphatase (Ap-A); phosphoglucomutase (Pgm-B); hexose-6-phosphate dehydrogenase (H6pdh-A); and fumarase (Fum-A). Variants for nine of these loci segregate as autosomally inherited codominant alleles. The other system, EST-C, does not reflect such inheritance. We have identified two possible linkage groups: H6pdh-A may be loosely linked to Pgm-B, and Fum-A appears to be linked to Pgm-A. Tissue specificity and intracellular localization for all these loci are also presented.
