CYTOGENETIC NOMENCLATURE OF DEER MICE, PEROMYSCUS (RODENTIA) - REVISION AND REVIEW OF THE STANDARDIZED KARYOTYPE - REPORT OF THE R-THE-STANDARDIZATION-OF-CHROMOSOMES-OF-PEROMYSCUS

A revision of the standardized karyotype of deer mice (Peromyscus) is presented. This revision addresses short-comings of the original stand ardization, contains a substantial increase in the number of G-band ma rkers and provides a nomenclature for the G-bands of each autosome and the X chromosome. Using the revised standardized karyotype, we specif y the particular G-bands or patterns that identify each chromosome and catalog the more problematic chromosome identifications and likely mi sidentifications. For each chromosome, we present an overview of previ ously reported variation in euchromatic arrangement and heterochromati c constitution. We then review previous applications of the standardiz ed karyotype and summarize the predominant findings from cytogenetic a nd cytosystematic studies of Peromyscus and related taxa.
