Abstract
1. On the shapes of the eye-lid(I), in the peculiarities in infolding the fingers of both hands(II), in the head hair-whorl types(III) and in the inward flexibility of the first joint of the thumb(IV) the writer investigated the frequencies of each character in genuine Japanese and in Coreans (the latter on I and II).
2. In four cases the double eye-lid(I), the right fingers upper infolding(II), the dextral head hair-whorl(III) are recognizable as probable simple Mendelian dominants over allelomorphs and the flexibility of the first joint of the thumb(IV) as a recessive.
