Characters and the systematics of Drosophilidae

Article Abstract:

Seven genera of the family Drosophilidae were studied for comparison of molecular and morphological data sets. This particular family was chosen because of the advanced stage of morphological analysis and the steadily increasing molecular systematics of the group. Furthermore, the molecular, genetic and developmental status of Drosophila melanogaster is far advanced and any developmental analysis can be applied to all members of Drosophilidae. It was therefore concluded that a study of the molecular and genetic basis of morphology and development in Drosophila will give valid data for the understanding of homoplasy in systematics,

The mtDNA genealogy of closely related Drosophila silvestris

Article Abstract:

A study was done on the genetic, morphological and behavioral characteristics of the rare Hawaiian Drosophila silvestris. Results from mating asymmetries showed that the northern Hawaiian species are ancestors of species found in the southern part of the island. A mitochondrial DNA (mtDNA) restriction site analysis further showed that the behavioral data was consistent with the mtDNA phylogeny.

RAPD diagnosis of the obscura group species symaptric with D. subobscura in North America

Article Abstract:

Drosophila persimilis, D. pseudoobscura and D. miranda are sibling subspecies of the pseudoobscura subgroup which is found only on the west coast of North America. A new study investigates the use of randomly amplified polymorphic DNA (RAPD) as a tool for classifying individuals of the subgroup pseudoobscura. Details of the study are presented.
