Since fruits are derived from the ovary wall or receptacle and hence are 
from maternal tissue, I would expect them to be reading maternal DNA as 
they develop.  So, why do I get strange "hybrid" squashes when I plant 
open pollinated varieties?  I can see how the seeds from this mating would 
produce hybrid fruits, but why the strange fruits in the "P1 generation"?  
Thanks for your help!
