Quantitative trait loci and interaction effects responsible for variation in female postmating mortality in Drosophila simulans and D. sechellia introgression lines
Article Abstract:
The reasons of reduction of the lifespan shortly after mating in Drosophila females are studied, using males from introgression lines between Drosophila simulans and D. sechellia genomes and a quantitative trait locus (QTL) mapping approach. It is found out that chromosomal regions affect postmating mortality of females meaning genes for reproductive traits other than hybrid sterility show evidence of epistatic effects when brought into a heterospecific background.

A multilocus microsatellite phylogeny of the Drosophila virilis group
Article Abstract:
A set of 48 polymorphic microsatellites derived from Drosophilla virilis is used to infer phylogenetic relationships in the D. virilis clade and special attention is given to the differentiation between D. americana texana, D. americana americana and D. novamexicana. F(sub ST) analyses show significant differences between these three groups.
