GENETIC VARIABILITIES IN SECOND AND THIRD CHROMOSOMES FROM KOREAN POPULATIONS OF <i>DROSOPHILA MELANOGASTER</i>

Genetic changes in a Korean population of Drosophila melanogaster.

“…These results are also shown in Fig. l together with previous results from 1957, 1962and 1967(Paik and his associates 1960, 1966, 1969. The differences between ours (C-L) and Choi's (C-P) were significantly large for the frequencies of deleterious chromosomes as well as those of lethal or semilethal chromosomes.…”

ANALYSIS OF GENETIC VARIABILITY IN THE TWO MAJOR AUTOSOMES OF <i>DROSOPHILA MELANOGASTER</i> IN A NATURAL AND A CAGE POPULATION

“…The natural populations of D. melanogaster seemed to contain similar frequencies of lethals on two major autosomes as Band and Ives (1961), Wallace et al (1966) and Allen (1966) reported by American populations, and also the tendency of the third chromosome to contain more lethals than the second chromosome was observed by Paik (1966) and Allen (1964) in a Korean small natural population and a Samoan natural population.…”

FREQUENCY OF DELETERIOUS CHROMOSOMES AND ALLELISM BETWEEN LETHAL GENES IN JAPANESE NATURAL POPULATIONS OF <i>DROSOPHILA MELANOGASTER</i>

“…Korean populations, studied by Paik (1960Paik ( , 1966, had similar values in the frequency of deleterious chromosomes (11.2, 15.2 per cent) and allelic rates (1.73 per cent). Thus, in these natural populations of Far East (Korea, Japan), the frequency of deleterious chromosomes was comparatively low and, in contrast, the allelic rate between lethals was rather high.…”
