Abstract

A survey of sixteen isozyme loci using electrophoretic techniques was conducted for three isolated natural populations and one laboratory population of the cyclic parthenogenetic species, Simocephalus serrulatus. The proportion of polymorphic loci (33%-60%) and the average number of heterozygous loci per individual (6%-23%) in the three natural populations were found to be comparable to those found in most sexually reproducing organisms. Detailed analyses were made for one of these populations using five polymorphic loci. The results indicated that (1) seasonal changes in genotypic frequencies took place, (2) apomicitic parthenogenesis does not lead to genetic homogeneity, and (3) marked gametic disequilibrium at these five loci was present in the population, indicating that selection acted on coadapted groups of genes.

摘要

利用电泳技术对周期性孤雌生殖物种锯缘真剑水蚤的三个隔离自然种群和一个实验室种群的16个同工酶位点进行了调查。发现三个自然种群中多态位点的比例（33%-60%）和每个个体杂合位点的平均数量（6%-23%）与大多数有性生殖生物中的情况相当。使用五个多态位点对其中一个种群进行了详细分析。结果表明：（1）基因型频率发生了季节性变化；（2）无融合生殖的孤雌生殖不会导致基因同质化；（3）该种群中这五个位点存在明显的配子不平衡，表明选择作用于基因的共适应组。
