Table 1.

Description of the association between species, Ldh genotype, reproduction mode (CP, cyclical parthenogenesis; OP, obligate parthenogenesis), presence of males, and the presence of diagnostic alleles associated with OP (see Table 3). The presence of OP diagnostic alleles in Ldh SF OP Daphnia pulex and Daphnia pulicaria is a result from the present study, whereas all other information is from pre-existing literature.
