Re: hybridizing

Linda,
I'll have to look back at basic biology books, but as I remember, as 
very small amount of non-nuclear DNA can come from the paternal side.
Not enough to worry about in a hobby of iris breeding, but enough to 
worry about if you're selling stud semen from a prize bull all around 
the world. The non-nuclear paternal effect could be all 
"pseudogenetic," as well. I can imagine that a pollinator which has 
slowly growing pollen tubes could give less vigorous seed, but the 
only example I know of this is governed by nuclear DNA (in a maize 
example). In this case, it could be nuclear and non-nuclear.
regards,
Steve
