What morphs make the Alienhead/keyholes disappear

I am still new to some of the effects of co-dominant morphs.

What morphs help lessen or make the alien heads/keyholes disappear in a morph.

Is it a lesser, or pastel group?

I have a lesser specter with no alien heads, same with a lesser enchi pastel yb fire.

Any help would be great!

The BluEL group (Lesser, Mojave, etc.) tend to alter the alien heads, sometimes removing the eyes, sometimes making them cyclops.

Enchi and OD tend to remove the eyes. Calico can do this as well

BlkPastel group tends to make cyclops


Awesome, thank you!
