Abstract:
The genus Drosophila has long been used as a model of karyotype evolution, demonstrating change by paracentric inversion and occasional centric fusion of an ancestral karyotype of five rod-shaped and one "dot" chromosome. This study shows, by mapping D. melanogaster probes hybridized to polytene chromosomes of Zaprionus tuberculatus, that this ancestral pattern extends beyond the genus Drosophila. A formal polytene chromosome map of Z. tuberculatus is presented.
