Piaffe - I have twins IRL so I know a bit about them, so bear with my lengthy rambling.
The ability to have FRATERNAL twins is genetic. It is passed to a female from her family. It is a genetic pre-disposition to release more than one egg in an ovulation cycle. It has nothing to do with the male half in a breeding situation - he can pass on the predisposition to his daughters, but can't make it happen in his mate. ALL chimeric horses that display two colours are fraternal twins.
Identical twins are random chance. There are lots of theories, but no one knows why the egg splits.
Hope this helps, feel free to ask because there is lots I know about twins lol.
Mods, grant me the serenity to see the opinions I cannot change, courage to change the ones that should change, and the wisdom to spot the trolls.
