Coral Glow/Banana Male Maker

I picked up a 1.0 Pastel Coral Glow from Tinley last weekend and was wondering if it is just to be assumed that all male CG/Bananas are male makers?

I noticed that most of the cases with these snakes were marked as "Male Maker" but a small handful were not. My new guy was not marked as such but I was so excited about him that I didn't think to ask the breeder if he was or not.

Also, does being a male maker mean that they cannot produce a CG/Banana female at all or does it just mean that they're not likely to do so?

Thanks!

If it wasn't marked you can be pretty sure it's a male maker as female makers are being sold at a premium. I sold one female maker this season and got twice the price of a male maker. You won't get all male bananas from a male maker but you will get 90% - 95% banana males with a banana female here and there.
