Abstract
Natural populations of Daphnia magna have been found which are polymorphic for electrophoretic variants of supernatant malic dehydrogenase, esterase, and alkaline phosphatase. Using these enzyme variants as genetic markers it has been possible to demonstrate the absence of recombination during parthenogenetic reproduction. Genetic uniformity is expected within parthenogenetic clones derived from a single female.
摘要
已经发现大型溞的自然种群在上清液苹果酸脱氢酶、酯酶和碱性磷酸酶的电泳变体方面具有多态性。利用这些酶变体作为遗传标记，已能够证明孤雌生殖过程中不存在重组现象。预计来自单个雌性的孤雌生殖克隆内具有遗传一致性。
