Title: Screwworm karyotyping and species diversity

Journal Article · · Am. Nat.; (United States)

The authors have reported morphological diversity in the chromosomes of screwworm populations, many of which were sympatric. The morphological diversity of the metaphase chromosomes allows cytogeneticists to identify the various heterozygotes and homozygotes. From such data it is possible to differentiate a mixture of populations through a Wahlund effect, and under certain conditions document the presence of distinct species. This discussion concerns the questioning by another researcher of the authors' evidence for the existence of gamodemes and cryptic species in the screwworm fly. The issues in question are explained.
