The frequency of second chromosomes bearing deleterious and sterile genes in the Banwoel natural population of DrosoPhila melanogaster was estimated in 1981. The results obtained were as follows. 1. The frequency of lethal and semilethal chromosomes was calculated as 28.83%. 2. Allelism rate among lethal genes isolated from Banwoel natural population was 1.84%. 3. The rate of elimination of lethal genes(IQ²) was estimated to be 0.15%. 4. The frequency of sterile genes on the second chromosomes was 6.87% for female, 5.43% for male. 5. Phenotypic sterile flies in the Banwoel natural population was 2.94%.
