second (09213) had the same seed parent as the last two families 
(og2tr and og212) under that case. The pollen parent in all three 
families of the present case was the same normal male, 0855(36), 
that was used for all the crosses in case V. It is consequently fair 
to assume that the differences in the result under case X and case 
XI are wholly referable to the male parent, and that such differences 
as appear between case X and case V are referable to the seed 
parents. There is no difference in the latter instance, while the 
fundamental difference in the former is that in case X the males 
were hermaphrodite, while in the present case they were normal 
males, thus showing again the correspondence between the male 
offspring and their pollen parent.

It will be recalled that among the 705 offspring produced in 
1909 from crosses between females and the genetic hermaphrodites, 
A and B, there were 2 males and 305 hermaphrodites. In similar 
manner it will have been noted that in a number of the cultures 
of 1910 a very small percentage of such males have appeared 
in families of which the male offspring were generally hermaphro- 
dite. Instances of this kind are noted above, under cases I, Ill, 
IV, V, VII, and X. Whether these males were true males or PpOS- 
sibly somatically modified hermaphrodites may now be considered. 
The families reported under the present case were produced 
by pollinating two different unrelated females with pollen of 
08118(13), one of the two males derived from genetic hermaphro- 
dite fathers in 1909. No hermaphrodites were produced, thus 
showing that the pollen parent was a true male, and not a hermaph- 
rodite which had suffered the suppression of the female organs 
because of some purely somatic influence. The frequency of 
occurrence of such male mutants may be inferred from the fact
