Jones: Heritable Characters of Maize 
are shown, and it can be seen that the 
same grade of defectiveness in the par- 
ents is reproduced in the offspring. 
Whether this is due to other factors 
in the plant determining the degree of 
development of whether there exists an 
allelomorphic series remains to be 
worked out.

The character, defective seeds, is a 
useful one in studies of linkage relations 
in corn, as it is a seed character and 
easily classified in most cases. It is also 
of interest because it is an illustration 
of defective germ-plasm, which is widely 
distributed in a cross-fertilized organism 
and has vital importance in life processes.

ORIGINAL LOT OF SELF-FERTILIZED EARS 
Original ears of the variety number 110 self-fertilized for the first time. 
17 and 18 are segregating for the defective seeds. 
Nos. 8, 12, 15, 
“Specimen No. 12 shows partially 
defective seeds, while in the one numbered 17 the recessive seeds are completely aborted. 
... In Fig. 9 some of the progeny ears of these two plants are shown, and it can be 
seen that the same grade of defectiveness in the parents is reproduced in the offspring.” 
(Fig. 15.)
