14. The ability of a seed to germinate seems to depend, not wholly, 
but to a certain extent, upon the number of chromosomes which it 
bears, and, possibly, in accordance with Gates's suggestion, upon the 
compatibility or incompatibility of the chromosomal combination 
which the number represents. 
15. The ability of a seed to germinate appears to be directly asso- 
ciated with its own chromosome number and onl}^ indirectly with that 
of its parent, for the results derived from the Cold Spring Harbor and 
Louvain studies indicate that 14-chromosome seeds of i4+-chromo- 
some forms germinate quite as readily as 14-chromosome seeds of 14- 
chromosome forms. 
16. Plants having more than 14, but fewer than 28, chromosomes 
are more inclined to be male- than female-sterile. Just why this is 
so, is not yet clear.
