초파리 자연집단내의 염색체 변이에 관한 연구 = On chromosomal inversions in Taejon natural populations of Drosophila melanogaster

다국어 초록 (Multilingual Abstract)

Taejon wild populations of Drosophila melanogaster have been studied for chromosome inversion polymorphism and fluctuation of its frequencies. A total of 3123 flies. 1546 males and 1577 females, were tested. All of the 14 inversion types found were identified to be paracentric and autosomal. Among them 7 were cosmopolitan and the rest endemic. The average of inversion frequencies was 0.81 and 0.54 in male and female respectively. The order of inversion frequencies of six cosmopolitans which were pooled together male and female samples in every year was 2Lt > 3RP > 2RNS > 3LP > 3RMo. The linkage disequilibrium were detected between left and right arm of 2nd chromosome in October of 1985. The nonrandom association appeared between 2nd and 3rd chromosome in October, 1986. The frequencies of flies carrying one or more inversions did not depart from the expected in male samples. On the basis of the present result. Taejon wild populations were good fitted to the Hardy-Weinberg equilibrium.
