Is the hairless a double rex or a full on hairless(recessive)?

Double rex hairless(patchwork) can breed together and the females can lactate.

I'm breeding double rex groups and doubles to single rex and doubles to regular hair.

The killer thing about double rex's are they look different about every molt they have.

This is one of my males...

And the following week, lol.

And now he looks like a Siamese, crazy! lol
