韓國人 隔離集團의 遺傳學的 硏究 = Genetic Studies on the Isolated Population in Korean

다국어 초록 (Multilingual Abstract)

This study has been carried out with the object of researching into the situation of the genetic isolation of a Korean population located near Seoul. The results obtained are summarized as follows: In general, the distribution of P.T.C. threshold values in the population is close to that of the Seoul population. But the nonataster frequency of male in the population is higher than that of female, and this is in agreement with the status of ankyloglossia frequency in male. However the relationship between the two traits has not been clarified. The gene frequencies of rolling and folding of tongue are slightly lower than that of the Seoul population. The gene frequency conditioning the ability to twist the tongue is lower in the male than in the female. The color-blindness is 6.21 percent, and it is slightly higher than that of other Korean population. All considered, the studied population might be regarded to have been kept in genetic isolation.
