When cross pollinating two different strains, the offspring will inherit 50% of the genetics of each parent plant.
A true hermaphrodite plant will generally produce hermaphroditic offspring if it pollinates itself, as it is a dominant gene.
If using pollen from a hermaphroditic plant to pollinate a pure breeding female plant, the resulting offspring will still have a minimum of 50% hermaphroditic offspring.
Generally, using pollen from a true hermaphroditic plant will lead to genetically compromised and inferior offspring regardless.
Personally, I have never and will never use a true hermaphrodite in any breeding experiments I may be undertaking. To me, a true hermaphroditic plant is the worst possible outcome, for it is useless to me with its inferior genetics. At least with a pure male, he can still be used for breeding and with total confidence in his genetics.
Hope this helps....
