Bloodred is codom?

The FAQ says "Bloodred is not truely a single recessive gene as it is co-dominant to it's wild-type."

How so? What can you see in a het bloodred to distinguish it from a normal? And if it is distinguishable, how come I've seen some "possibly het bloodred" snakes for sale?
 
Bloodred is, for the most part, simple recessive. In it's heterozygous form there are a couple of indicators that are not always present: Increased red coloration as well as a white stripe of varying width down the belly. That's a simple version, someone else may have something more in-depth to share with you.

Thanks for the reply!

Our little girl definitely seems to have more red than an average normal, but since she's half okeetee, I had assumed her richer color came from that.

She also seems to have... I guess I'd call it more of a separation between some of her belly checks than really a "stripe". I hadn't thought of it as anything unusual. Guess I need to pay more attention to those belly pics when I see them!

Anyway, whether or not this counts as the the het bloodred markers or not, I trust the breeder I got her from and according to him she is 100% het, so I'm not worried about her. It would be useful when I get to the point of her having babies to be able to recognize het bloodreds! So if anyone else has more to add I'd appreciate it.
 
The codom idea is not really a proved out idea yet. The het traits that people talk about are varring degrees of normal. The little bit diffused side patters on a normal does not necessary mean het bloodred. It very likely is nothing more than a family or line-bred trait and not genetic.

Diffused side patterns and elongate head patterns are important, but the real test is the lack of belly checkers. Then you have homo blood red.
