Research in my laboratory focuses on the expression of isozymes during the development of interspecific hybrid fishes. These studies relate the divergence in the regulation and expression of multilocus isozyme systems in interspecific hybrids with those of the parental species utilized in forming the hybrids. Additional studies involve the determination of inheritance patterns for coloration and banding phenotypes in teleostean fishes and the genetics of Sceloporus jarrovi populations.
