Abstract: | The mangrove rivulus, Kryptolebias marmoratus (Rivulidae, Cyprinodontiformes), is phylogenetically embedded within a large clade of oviparous (egg laying) and otherwise mostly gonochoristic (separate sex) killifish species in the circumtropical suborder Aplocheiloidei. It is unique in its reproductive mode: K. marmoratus is essentially the world's only vertebrate species known to engage routinely in self‐fertilization as part of a mixed‐mating strategy of selfing plus occasional outcrossing with gonochoristic males. This unique form of procreation has profound population‐genetic and evolutionary‐genetic consequences that are the subject of this review. |
