enzymatic variation at seven loci in nine natural populations of drosophila melanogaster.	allozyme polymorphisms at seven loci have been studied in nine natural populations of drosophila melanogaster from the saône and rhône valleys sampled in 1973 and 1974. a great deal of polymorphism was observed; an individual was on the average heterozygous at 20.2% of its loci. the populations were genetically very homogeneous throughout the region sampled. the number of ovariolae per female varied from one group of populations to another depending on their geographical separation. yet the numb ...	1977	406898
comparative evolution of p-m system and infection by the sigma virus in french and spanish populations of drosophila melanogaster.	in 1983, an extensive survey of populations of d. melanogaster was started in a southern french region (languedoc) in two non-mendelian systems: the p-m system of transposable elements and the hereditary rhabdovirus sigma. unexpectedly fast-evolving phenomena were observed and interesting correlations were noted, giving similar geographical pattern to the region in both systems. for these reasons, the analysis was continued and extended towards the north (rhône valley) and the south (spain). in ...	1992	1334901
