say the BlkEL is a fire/fire and the BEL is a Lesser/Lesser
you would get Lesser/Fire
say the BlkEL is a Fire/Sulfur and the BEL is a Butter/Mojave
you could get the following
Fire/Butter
Fire/Mojave
Sulfur/Butter
Sulfur/Mojave
Now you next question is going to be what if I take the two fire/lesser and breed them together and hit on the double Lucy, what does it look like? We don't know. my guess would be the Black eye would dominant over the blue eyes, but it hasn't been done (to my knowledge) so we don't know for sure.
