The C32 isogenic homozygous diploid (IHD) strain of the zebrafish (Danio rerio) was found to be polyallelic at a malate dehydrogenase locus (sMdh-A). A variant allele is thought to have arisen via mutation within the past 10 bisexual generations that have maintained the strain since its last gynogenetic cloning event; this unique allele now predominates at the sMdh-A locus. The estimated mutation rate in this species is sufficiently high that long-term genetic homogeneity of its IHD clones cannot be assumed. Researchers using such bisexually maintained clones should be aware that they are not necessarily using genetically uniform subjects. Genetic uniformity of cloned IHD zebrafish will be maximized if experimental subjects are obtained soon after a cloning event. IMAGES:
