1. The factors for the white margin in the Japanese morning glory are:
F^a, f^a F^b, f^b>F^a and F^b work complementally for the fomation of the white margin. Neither factor can produce the white margin by itself.
F^b, f^h-F^h acts as a complete inhibitor.
F^f, f^f-F^f acts as a partial inhibitor.
2. f^a links with d (contracta) in about 1% of crossover, and f^b with n_n (Nandina) in approximately 0.5%.
3. F^f links with c (white flower with colored stem), the frequency of crossover being roughly 20%.
