Aldolase C polymorphism in the laboratory opossum, Monodelphis domestica

A two-allele polymorphism in aldolase C was identified in brain extracts of grey short-tailed opposums, Monodelphis domestica, by electrophoresis in starch or cellulose acetate gels. Pedigree data were consistent with autosomal codominant inheritance. The polymorphism was present in two of the six genetically distinct laboratory populations that have been established for this species.
