传统上，石珊瑚通过扁平幼虫的繁殖被视为严格的有性过程。在这里，一个无处不在的印度-太平洋珊瑚，Pocillopora damicornis，电泳研究的结果显示了一个确切的遗传父母的基因型由育雏planulae，表明存在的无性模式生产的planular幼虫。一些种群的遗传结构与预测的有性生殖结构的比较表明，虽然可能也有一种有性生殖形式，但无性繁殖产生的浮浪在维持本物种种群方面可能具有重大意义。
The reproduction of scleractinian corals through planular larvae has traditionally been viewed as a strictly sexual process. Here, the results of an electrophoretic study of a ubiquitous Indo-Pacific coral, Pocillopora damicornis, show an exact inheritance of parental genotypes by brooded planulae, demonstrating the existence of an asexual mode of production of planular larvae. Comparisons of the genetical structure of a number of populations with structures predicted for sexual reproduction suggest that, although there is probably also a sexual form of reproduction, asexually produced planulae can be of major importance in the maintenance of populations of this species.
