The Va/Ba balanced lethal strain: thirty years of research in Drosophila subobscura (1977–2007)

O-chromosome lethal frequencies in Serbian and Montenegrin Drosophila subobscura populations

“…In D. subobscura, studies of lethal genes have been possible since Sperlich constructed the Va/Ba (Vari cose/Bare) balanced lethal strain [17,18], in which many molecular markers have recently been charac terized [19]. Most analyses have focused on the geo graphical distribution of lethal frequencies, both in Palearctic and American populations (see [5] for a re view).…”
