theoretically 2'9 : 5\S : 5 - 8 : ll - 6 respectively. Furthermore, we have 8 homo 
(CCrrbb ) and 11 heterozygous oranges (Ccrrbb), theoretically 6 - 3 and 12-6 
respectively. Besides, all whites are considered to be homozygous, as above 
t That the appearance of 2 reds in the offspring of this No. which is considered to be of 
the genotypic constitution GclirJib is due to the formation of a certain number of the 
gametes CrB, Glib, crû, cTZb, i.e. to the change of the complete coupling ” between 11 
and li into a partial, will be discussed p. 123. The appearance of 1 red in F 2 (s. Table 
VI, A, white-II x orange. No. 2) may also be due to the same cause.
