Abstract

Comparison of inversion polymorphism in Drosophila lummei populations from Finland (Kemi) and Russia (Rybnyi) revealed additional species-specific paracentric inversions in chromosomes 2-4. The newly found inversions, 2V, 3M, 4U, and V, were reported only for the Russian population. The 2U inversion had been earlier detected in D. lummei and in the second chromosome of a D. ezoana population from Kamchatka. Species-specific 5T inversion from the Finland population was not found in the Russian population. 4R, S, and 5S inversions were common for both populations but had different sample frequencies. 4R and 5S inversions were more frequent in the Finland, and 4S in the Russian population which may indicate their different adaptive values in these areas. All inversions except 3M were localized in subterminal chromosome regions. 3M inversion was localized in the submedian region.

摘要

对来自芬兰(凯米)和俄罗斯(雷布内伊)的卢氏果蝇种群倒位多态性的比较揭示了2号至4号染色体中额外的物种特异性臂内倒位。新发现的倒位,即2V、3M、4U和V,仅在俄罗斯种群中被报道。2U倒位此前已在卢氏果蝇以及堪察加半岛的伊氏果蝇种群的第二条染色体中被检测到。来自芬兰种群的物种特异性5T倒位在俄罗斯种群中未被发现。4R、S和5S倒位在两个种群中都存在,但样本频率不同。4R和5S倒位在芬兰种群中更常见,而4S在俄罗斯种群中更常见,这可能表明它们在这些地区具有不同的适应价值。除3M外,所有倒位都位于染色体亚末端区域。3M倒位位于亚中部区域。
