Morphs

[jdhutton2000]

Is it just me or does it seem like there are becoming more and more normal that have names? I think I hit my point when I started seeing Yoda and Jedi lines... smh. I love star wars, but they look like normal with some cool qualities..

I love on here when we point out morphs we say " Normal with high gold" or "Normal with reduced Pattern" or "Normal with nice yellows and high contrast black"

I really think we need more of those. Cut back on all the stinking morphs... I think normal should have a +/- associated with them! Would seriously reduce the amount of "Morphs" out there.

*2 cents*

It depends on the morph. Look at a specter for instance... most people can't differentiate one from a normal. Look at a super specter and there's no doubt that specter <> normal.

I like to call my 1 normal Classic =) so she dont feel so bad!


And yea theres quit a few that look normal, even some spot nose, or some enchi's or low quality fires,, there alot out there that LOOK normal but proven out to not be!

For a "Normal" to be listed as some sort of morph, it needs to have a trait that is inheritable to approx 50% of its offspring (by Mendelian genetics math), and that continues to be inheritable for the subsequent generations. This is how you differentiate a polygenic phenotype that one snake may have (due to the stars aligning with its overall genetics code), vice a single gene anomoly.

If this anomoly is inheritible, it is something. If a "Normal" has a very reduced pattern and so do some of it's babies, and grand-babies, etc... then is is a Genetic RP, which is a morph.

As more folks are breeding, and line-breeding is coming in to favor for Balls, you will see more discussion about this. Many folks have developed an eye for subtle changes and then breed those animals to see where is stands genetics-wise (polugentic vs inheritable single mutation). One of the BIG problems is folks that do nto do the due diligence to look for a Super form or to see the project for a couple of generations before slapping a name on it and marketing it.

Also, just because the average person does not see the mutation in its Heterzygous form, does not mean it is not there. At this point folks that breed Specters, Gravels, etc.. can easily pick them out in a clutch.

some of the morphs that we call codominant / incomplete dominant might just as well be called recessives.

for example, the white diamond / russo leucistic is a recessive trait. as in, to get the white snake, you need the homozygous form. but it turns out that while "het russo", the heterozygous form, is really really subtle, people are able to pick them out of a clutch. so now we call it codom, with the white diamond being the super form, but we still call the heterozygous form "het russo".

viewed as a codominant, "het russo" is really really subtle, but the very obvious super form, the white diamond, completely justifies it.

I can't speak for the projects you do or don't want to get into or invest in but I do have to say ALOT of the Ball Python morph originators do not no how to promote and advertise or create hype.

Alot of these morph names are baaadddd. Just tacked on and not making much sense. I digress.

For it to be recessive it can not combine with another gene that is incomplete dominant and produce a white snake as well. Breed a het russo to anything else in the BEL complex and u get white snakes so it is in fact incomplete dominant.

For the purposes of this discussion, codominant and incomplete dominant are synonyms.

The terms dominant, codominant and recessive do not describe an inherant property of a given gene. They are comparative. It is quite possible for one gene to be dominant to a second gene, recessive to a third gene, and codominant to a fouth. For example, the lesser mutant gene is codominant to the corresponding normal gene and dominant to the mojave mutant gene. Lesser is codominant to the normal gene because you can tell the difference between a snake with two lesser genes, a snake with two normal genes, and a snake with a lesser gene paired with a normal gene. Lesser is dominant to the mojave gene because you cannot tell the difference between a blue-eyed white snake with two lesser genes and a blue-eyed white snake with a lesser gene paired with a mojave gene. While a snake with two mojave genes has some pigment on the head and neck.

The point I'm trying to make is that the classification of the russo gene compared to lesser (for example) is irrelevant to the classification of the russo gene compared to the normal gene.

Thank you. This is true, but it seems very few people (in reptiles and in general) understand this.

It is usually safe to talk about a gene being recessive (or dominant, or codom) and just let the assumption be that we are talking about in comparison to the normal gene. But in cases where there are more than 2 choices on the same loci, such as in the BEL complex, it gets much more complex.
