what is dilute? diffusion?

I'm still somewhat unfamiliar with a few morphs and had a question. I've been seeing snakes that are dilute...and snakes with diffusion. I'm wondering what is dilute and what is diffusion. Are they heritable morphs? How does it affect the snakes color?

Thanks,
 
Dilute is a gene that is fairly recently identified. It gives a "Blued Steel"/Pinkish appearance to Anery morphs. It's most commonly associated with Anery Motley's but I know there's some pictures around here of Normal Dilutes as well. Do a search for Dilute in the picture gallery and you'll get quite a few examples.

"Diffused" is a term used to describe the Bloodred gene which is a pattern mutation.

Both are heritable and appear to work as simple recessives, though Bloodred does appear to show "markers" sometimes in het animals. It doesn't happen commonly or accurately enough to be completely reliable.

Dilute works as a simple recessive ... and more is being learned each day.

As it appears, Dilute was first discovered/noticed in Anery based morphs (Anery &/or Ghost).
So, since only Anery based Dilutes were being produced (&/or given recognition), people believed it only existed (or could exist) in Anery based morphs ... some folks still do. However, this is not so.
Dilute can be carried by, and does affect, other morphs as well.
Aside from Anery based morphs, and since the time of first recognition (of Dilute),... Dilute Classic, Dilute Caramel, Dilute Amber, Dilute Charcoal, & Dilute Hypo have also been produced.
I have no doubt that other morphs (than these listed) can carry/exhibit Dilute as well.
With time, we are very likely to see more.

For more info, about Dilute, see: http://www.cornsnakes.com/forums/showthread.php?t=71169
BTW There is mention, in the thread, of a "haze" that can be seen on Dilutes ... it is, actually, more of something that can be "noted" (IOW it is not a "painted on" haze but does give a "softened" look). Not sure if that makes sense but it is not an easy thing to describe.
Also, you can see a comparison of a yearling Dilute Classic, with yearling regular Classics, here: http://www.cornsnakes.com/forums/showthread.php?t=71896
 
so from what I gather...bloodred is a reference to the pattern mutation (like motley and stripe) as opposed to the color? or does color also play a part in the bloodred morph?

also, when I see "bloodred poor diffusion" what does that mean exactly?
 
People refer to how well the snake is diffused. The diffusion is the color that's missing or smeared or diffused, seen best on the snakes side.

What these terms mean to different people though is not the same. I know that's not what you wanted to hear, but since there is no governing body in this hobby people use the terms they want to, and pretty much however they want to, lol.
You can get the idea of what people mean though.. Someone may say
A. 'this snake is a blood, but doesn't have very good diffusion',
that's kind of the same as someone else saying:
B. 'this snake is diffused, but I wouldn't call it a blood.'
In these examples, person A considers bloodred to be the diffused gene for the most part, person B considers bloodreds to be a line bred morph that has diffusion in the mix. What both of those people agree on is that the snake they're talking about isn't very diffused.
I don't think it matters either way, people will know what you are talking about if you are specific.

Click to expand...

Those who distinguish between "Bloodred" and "Diffused" only use Bloodred for Blood/Diffused exemplars that exhibit the red coloring ... and Diffused is used for any non-red colored snake with the diffusion/blood gene (i.e. Anery Blood, Charcoal Blood, Lav Blood, etc., plus Classic Bloods that are not red in color).
'Course, then there are those who use "Diffused" for all Blood morphs (regardless of color) ... and those who use "Bloodred", or "Blood", for all Blood morphs (regardless of color).

Diffusion is the blurring/smearing/disappearance of the side pattern.
The more side pattern, or clearly seen side pattern, or the least blurring/smearing/disappearance (of the side pattern), would be considered poor diffusion.
Very nice examples, of adult bloodreds, should have no side pattern and the diffusion effect would affect the lower sides, of the dorsal saddles (by blurring them out), as well.
