title: Linkage relationships of nine enzyme Loci in sunfishes (lepomis; centrarchidae).
abstract: Linkage relationships of nine enzyme loci; aconitase (Acon ), esterase (Est), glucosephosphate isomerase A and B ( Gpi), glycerate-2-dehydrogenase (G2dh), malic enzyme (Me ), phosphoglycerate kinase (Pgk), phosphoglucomutase (Pgm ) and superoxide dismutase (Sod), were investigated in sunfishes (Lepomis, Centrarchidae). Reciprocal F(1) hybrids produced from crosses between green sunfish (Lepomis cyanellus) and redear sunfish ( L. microlophus) were backcrossed with each of the two parental species. A three-point linkage map comprising G2dh, Pgk and Sod is reported. The frequencies of recombination between G2dh and Pgk and between Pgk and Sod are estimated as 45.3 and 24.7%. The remaining six loci assort independently. Possible linkage conservation and homology of this linkage group with those of other vertebrate species are discussed.
