The transmission of meiosis suppression in Daphnia pulex. (A) The Ldh SF and SS obligately parthenogenetic (OP) D. pulex hybrids can originate from backcrossing between F1 cyclically parthenogenetic (CP) hybrids of Daphnia pulex (white) × Daphnia pulicaria (grey) with D. pulex males carrying meiosis-suppression genes. Stars indicate obligately parthenogenetic individuals. (B) Females of pure D. pulex can mate with Ldh SS OP males with some D. pulicaria genes, giving rise to both CP and OP offspring with some D. pulicaria genes (grey).
