韓國 섬 集團에 있어서 노랑 초파리(Drosophila melanogaster)의 P-M System에 의한 Cytotype 決定 및 알코올탈수소효소(ADH) 活性度 分析
金彧,馬皓銓 단국대학교 1992 論文集 Vol.26 No.-
Cytotype distributions from three island populations(Cheje isl., Yeongjong isl., Ulnung isl.) of D. melanogaster in Korea were examined. It was also conducted to compare the differences for the ADH activity and lethal gene frequencies among strain types. P activities of three island populations were found to be very low. There were mainly M' and Q cytotypes in three island populations. These results suggested that the cytotype polymorphism could be maintained in those populations. The frequencies and patterns of cytotype distribution were very similar to the results of other reports. It might be interpreted as the results of migration between these islands and mainland or some forms of natural selection. The differences of ADH activity among strain types were found to be not significant, though the activity of M' strain was somewhat higher than that of Q strain. The frequencies of recessive lethal genes appeared to be nearly same among strain types, though lethal gene frequency of M' strain was slightly higher than that of Q strain.
