Reconstitution of Diploid Ambystoma jeffersonianum (Amphibia: Caudata) in a Hybrid, Triploid Egg Mass with Lethal Consequences

A. S. Taylor

Department of Zoology, University of Guelph Canada

Abstract

A naturally occurring mole salamander egg mass gave rise to both triploid Ambystoma laterale-(2) jeffersonianum and diploid A. jeffersonianum. Through the use of electrophoretic and cytological markers it was determined that the diploid salamanders were reconstituted from a maternal genotype of A. laterale-(2) jeffersonianum. This reconstitution proved lethal in all of the diploid offspring. One diploid salamander that survived long enough to be karyotyped was found to have considerable karyotypic anomalies, which were not present in its triploid siblings. These findings are expected to have implications with respect to introgression, embryonic survivorship, and population structure within the A. jeffersonianum complex.
