Abstract
The sasang constitutional medicine has been believed to be inherited. To ensure the heredity of sasang constitution and to look into the heredity pattern, we statistically analyzed constitutional relationship between parents and their children, using 173 clinical data couples registered to SCIB(Sasang Constitution Information Bank). The following results are obtained: The sasang constitution can be believed to be inherited, because the constitutions of children, whose parents have same constitutions, are mostly the same as their parents'. And it seems that one constitution is predominant to the other according to combinations of constitutions because constitution ratio of children are uniformly 2 to 1 in case the constitutions of parents are not same. Also it was confirmed that any sex of parents is not predominant by Chi-square test.
