Albumin and post albumin types in korean cattle were investigated by means of starch gel electrophoresis. 1) The distribution of Alb phenotypes in 108 korean cattle was Alb-AA type 105 and Alb-AB type 3. The Alb BB type has not yet been reconiged in korean cattle. The gene frequencies were Alb^A=0.986 and AIb^B=0.014. The gene Alb^C and Alb^B, which have not been reconiged in european cattle, were found at relatively high frequencies in formosan yellow cattle, at low frequencies in korean cattle, and very rare in a Japanese breed. According to these results it is supposed that Japanese native cattle originated from korean cattle, and these two breeds might have been somehow influenced by yellow cattle. 2) The distribution of Pa phenotypes in 107 korean cattle was Pa-AA type 9, Pa-AB type 49 and Pa-BB type 49. The gene frequencies were Pa^A=0.313 and Pa^B=0.687.
