Abstract
|
|
|
The frequency of second chromosomes bearing deleterious genes in the Ulsan and Anyang natural populations of Drosophila melanogaster was estimated by using of Cy/Pm method.
1. The frequency of genetic sterility genes was estimated to be 7.16% for females, 6.25% for males, 2.70% for both sexes in the Ulsan and 9.10% for females, 7.48% for males, and 2. 10% for both sexes in the Anyang populations from 1974 to 1978. As a rule, the data for the Ulsan population was lower than those of Anyang.
2. The frequency of phenotypic sterility genes was estimated to be 6.17% for males in the Ulsan and 6.64% for males in the Anyang populations from 1974 to 1978. As a rules the data for the Ulsan population were lower than those of Anyang.
3. The frequency of sterility genes on second chromosomes concealed in Korean populations were lower than those in American and Japanese populations. As a rule, the Korean population size was smaller than those in American and Japanese populations.
