• The Japanese Silky fowl is quite remarkable in being polydactylous generally having five toes on each feet.In the cross between the Silky fowl and White Leghorn breed having four toes, the inheritance of polydactyly was studied in this work.1) The F1-offsprings obtained from the Silky fowl×White Leghorn showed to be always polydactylous without exception (see Table 2).2) In the F2-generation, polydactylous fowls and normal fowls were produced in the ratio of approximately 3:1 (see Table 3).3) Segregation in the FR1-generation (back-cross) was found to be polydactyly, 1: normal, 1 (see Table 4).4) From the above results obtained, it is evident that the polydactylous character has been inherited as a Mendelian, autosomal dominance, so far as the scope of the present experiment is concerned.
