Any verdict on ultramels, burgandy, Bells, Criders. etc

I was just curious if there is any information on crosses between these caramel morphs. Has anybody found out if any of these crosses result in homozygous babies? The only threads I've found are a few years old. Surely somebody has made some of these crosses by now. Oh let me ask one more. Who introduced the ultramel and when.

well Camarillo proved Caramel Albino and Ultramel not the same. also bells is the ultramel. Cirder is believed to be the same morph.

None have proven compatible so far...

Ultramels have been around for a while...They were once just called "African Line" Caramels...They are not compatible with Caramels though.

One breeding has been done with Ultramel visual x Crider line 100% Het...All normals.
