Looking for expert opinions

Hey, so I'm still not very savvy when it comes to identifying various corn snake morphs so I wanted to get some thoughts on one of my adult females. She was a PetCo find and I got her as a baby and I have always thought of her as a normal/wild type. As she grew she seemed to have less and less pattern and got deeper and deeper red in color, like what I think of as diffused/bloodred. The odd thing to me is her belly pattern, which still has the black and white checkers towards her head but about halfway down her belly is like this tomato orange color. When I breed her, her "normal" babies do the same thing. I'm not a photographer, but I am adding some pictures below to illustrate what I mean. The first 2 are of one of her babies (she was bread to an anery with no hets that I am aware of). This is how she looked when I got her. The second 2 are of one of her yearlings (same paring) and the last 3 are of her. So again, newbie to genetics here just looking for an expert opinion. Thanks!

The masking of the black reminds me more of red coat, but my experience there is limited. Curious to see opinions from someone who does work with RC.
 
I have no idea how to differentiate between red coat and red factor visually, but the fact that she had babies with a similar appearance makes me think red factor (because it's dominant, right?).
 
The way it's always been described to me is that red coat is a top coating of red pigment which can mask some of the markings whereas red factor pumps up the reds in the background.
 
Interesting that you say she looked pretty normal when she was small, I would expect redcoat and red factor to be more obvious at that age? Do you have any baby pics of her from around the time you got her?

It's possible... I need to do some digging though.
 
I do agree with the assessment she's probably red factor though, since she produced such red animals when mated to an unrelated animal, consistent with a dominant trait.
 
So is red coat recessive then? I was under the impression it was at least incomplete dominant or something. I guess that's just red factor then?

What are your future plans for these guys? I wouldn't mind picking up a hatchling sometime down the road for a bit of testing. I've been debating about bringing one of the red genes into a future project.
 
I think redcoat is recessive, and that the animal in question here seems red factor.

Steve says the results in his collection are consistent with redcoat being recessive. People that work with red factor see results consistent with incomplete dominance.

I have redcoat and red factor in my collection so am interested in working them both into other morphs. But red factor seems like much less of a hassle due to it being dominant.
 
If that's the case, I definitely agree about being less of a hassle. I know I want to bring my cayenne fire's red factor into a project or two, though if this is the same gene it might make sense to have a more...er, "pure" project animal? Otherwise the original female is a normal with possible unknown hets, right? I mean that yearling holdback is just stunning on its own.
 
I'm going to say Red Factor, because of the fact some of her babies ended up with the red.
Red Factor does diffuse some of the patterning.

Here is Cinaed, my first experience with RF.
I saw something different about him, and contacted John F about him.
As he grew, the red wash became more intense, and his Tessera pattern became more diffused.

He is a Red Factor Tessera het for Amel Bloodred. His Dam was a Cayenne Fire.
He sire a clutch of babies two eyars ago, and the RF doesn't always show up immediately, I found. Some that I didn't think were RF, started developing the RF wash.

The last pic is his son, Sol, a Sunglow Tessera (RF Amel) het Anery poss het BR

I expect that if we saw baby pics of this snake, we'd be able to tell that it was red factor, but it may not have stuck out at the time without this knowledge since the difference is more subtle in babies. I wouldn't expect her to have had the gray ground color of her offspring in the first pic.
 
Could she be the non-amel version of a sunglow? that morph is Amel, selectively bred to show no white (IE no black borders if the amel was removed) Couldn't this snake be a non-amel version of that morph? She looks to have dark eyes, but her belly checks are dark but not 'black' looking. or maybe with Hypo?
