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.
淀粉凝胶电泳表明,野生的异鳞底鳉种群中至少有21个基因座存在电泳变体。我们提供了10个多态系统的遗传数据:酯酶(Est-B、EST-C和Est-D);天冬氨酸氨基转移酶(Aat-A和Aat-B);甘露糖磷酸异构酶(Mpl-A);酸性磷酸酶(Ap-A);磷酸葡萄糖变位酶(Pgm-B);6-磷酸己糖脱氢酶(H6pdh-A);以及延胡索酸酶(Fum-A)。这些基因座中有9个的变体作为常染色体遗传的共显性等位基因进行分离。另一个系统EST-C并不反映这种遗传方式。我们确定了两个可能的连锁群:H6pdh-A可能与Pgm-B松散连锁,Fum-A似乎与Pgm-A连锁。同时还介绍了所有这些基因座的组织特异性和细胞内定位情况。
