Re: RE:Hyb: Cytoplasmic inheritence was disease resistance

I know that in African violets there are leaf varigations due to different genetics.
One, the most commoonly used by breeders, is cytoplasmicly inherited.  Other genes on the chromosomes modify the amount and location a little, but the presence or absence is strictly due to cytoplasm.  This form is also highly modified by the temperature a given plant is grown at.
Another type is strictly due to a simple recessive gene.
It seems there is at least one other varigation, also due to a nuclear gene.
 
And at least in pearl millet, chlorplasts can be passed through the pollen.  This is a rare exception to the norm that pollen does not carry chloroplasts.
This has been found in two or three other species.  Again, this is not the norm.
