[Shrek] How did Donkey manage to get Dragon pregnant?

Are Dragon anatomy and genetics really that compatible with the donkey counterparts? We know they didn't adopt or use a surrogate, because the offspring were Dronkeys. Does their success in breeding have anything to do with Donkey's use of the Happily Ever After potion?

I need to know!

In the world of Shrek, procreation isn't based off of something as silly or far-fetched as genetics. Any two people of opposite gender can procreate as long as they share that most important and divine aphrodisiac; True love.

Conversely, people who aren't truly in love cannot reproduce, even if they had compatible parts. (Villains may be an exception to this rule.)
