Notes
Data exist suggesting both the presence and absence of recombination in monogonont rotifers. It was therefore previously unknown whether members of this group have true sexual reproduction. We have used acrylamide gel electrophoresis to identify clones of Asplanchna girodi homozygous for two different alleles at a single malic enzyme locus. Crosses made among these clones produced heterozygotes, thus demonstrating that classical sexual recombination occurs in this group of rotifers.
