Title: | Inbreeding reveals interpopulation differences in inversion polymorphism of Drosophila subobscura | Authors: | Rašić, Gordana Stamenković Radak, Marina Savić, Tatjana Andjelković, Marko |
Keywords: | Coadaptation;Drosophila;Homozygosity;Inbreeding;Inversion polymorphism | Issue Date: | 1-Feb-2008 | Journal: | Journal of Zoological Systematics and Evolutionary Research | Abstract: | The adaptive significance of inversion polymorphism of Drosophila subobscura is well established. However, little is known about gene combinations within inversions which are coadapted because of population-specific effects. We studied this aspect of Dobzhansky's coadaptation hypothesis, using the systematic inbreeding method. Differences in magnitude and quality of inversion polymorphism in two ecologically and topologically distinct habitats were compared after several generations of continuous full-sib inbreeding. Populations from the two habitats differ in frequency of homokaryotypes after third and fifth generation of inbreeding and in the levels of homozygosity of different gene arrangements. The effect of homozygosity appears population and chromosome specific. © 2007 The Authors. |
