. Biology of the Heteromyidae. Heteromyidae. BIOCHEMICAL GENETICS James L. Patton and Duke S. Rogers Introduction General Content and Perspective. This review will focus on the degrees of genetic variability and differentiation at the population and species level in het- eromyid rodents. Aspects of phyletic relat- edness among species within genera will be considered as far as the published literature permits, but the general questions of the definition of major clades and their rela- tionships within the family, and within the Geomyoidea, based on biochemical data, will not be addressed here.

These are topics that other review chapters can deal with more effectively and more comprehensive- ly. The title of this chapter is misleading, however, as it suggests that a more com- prehensive knowledge of the biochemical genetics of heteromyid rodents is known, and will be summarized here, than is in fact the case. Indeed, and with very few excep- tions (, Hafner, 1982; Thomas et al., 1990), the only biochemical methodology that has been applied to aspects of hetero- myid biology is that of protein electropho- resis (isozyme and allozyme analyses). Moreover, the scope of the questions asked in the published studies has been both nar- row and descriptive in content, centering only on (1) amounts of within and among population genie variation as measured by this approach and (2) suggestions of phyletic relationship among taxa within and among the recognized genera in the family. Most studies are relatively old, at least in the con- text of the time frame over which protein electrophoresis has been applied to these issues. More recent developments, includ- ing both empirical and theoretical advanc- es, are therefore generally lacking from the existing heteromyid literature on this topic. Clearly, much work remains to be accom- plished, and the recent developments in DNA sequencing and fingerprinting offer considerable excitement for future studies. Hence, the data summari
