o Cultures containing an excess of nonrogues over rogues. The noufogues were comparable to the 
intergrading intermediates described by Bateson and Pellew (i). 
Of the 184 Fj plants, 52 had progenies containing (i) only broads, (2) 
both intermediates and broads, or (3) intermediates only; i. e., they 
were recessive for the X factor but may have contained the Y or y factor. 
There were 86 progenies which segregated into rogues and nonrogues; 
while the progenies of 46 plants were all rogues (Tables XVI to 
XVIII. The observed number of XX : Xx' Fg segregates is very close 
to that theoretically expected (Table XIX). 
Inspection showed segregating families to be of two kinds: First, 
those with an excess of rogues over nonrogues, and second, those with 
an excess of nonrogues over rogues. In the latter case the nonrogues 
were often comparable in appearance to the intergrading intermediates 
described by Bateson and Pellew (2). Fxcept in cultures containing a 
very few plants, one would not expect such an excess of recessives as 
was found in these families.
