Abstract

|
|
The genetic variabilities of second chromosomes of Drosophila melanogaster concealed in Busan natural and experimental populations have been analyzed by the Cy//Pm method. The experimental population was composed of D. melanogaster which had the lethal-free second chromosome, collected Sasang natural population in 1982. The frequencies of deleterious genes were estimated to be 14.3～25.4% in Busan natural population and 26.5～27.2% in experimental population. The allelism rates in lethal genes isolated from the natural and experimental populations were calculated to be about 0.76% and 9.76～14.17%, respectively. The value of elimination by the frequencies of deleterious genes and allelism rate was 0.0106 and the effective population size estimated to be about 430 flies at the 6570 days population.
