Het = Heterozygous in short meaning 1 gene
Homozygous in short means having 2 genes (genes comes in pairs of 2)

So het red axanthic has 1 gene and the red axanthic has both genes. Pastel, Lesser, Cinny, ect. are all heterozygous aka hets. all morphs are heterozygous or homozygous, doesn't matter if their visual or not, dom, co-dom, or recessive.

So when you bred your BB did you also get non-BB animals in the same clutch?

According to RDR (If I remember correctly) a het red is (BBxBB) which would make a het red a Homozygous morph. A Red Axanthic would be a super form. Like I said I cant remember 100% but im pretty sure thats what it said.

I have not produced any BB myself, you would be better off asking Rabernet. I do have a BB male just havent bred him. Just never had a good female to put him to.
