Enigma ?

[im faster]

OKay my buddy just hatched out 2 geckos
and asked a question since i dont mess with enigmas i need help


SHT X Tang enigma

He said one looks normal and one is Enigma

So is the other Het enigma?

 

[rumbolt]

No if he does not show it, it isnt enigma at all. Enigma atm is considered a dominant morph I do believe.

 

[fl_orchidslave]

Maybe I'm not correct in my understanding, but if enigma is considered a dominant gene, wouldn't there be a het? So I think of it like the snow gene, a co-dominant, in that it either is or it isn't, without possible het. Hopefully someone can clear this up.

 

[rumbolt]

i treat it as a co-dominant as well since it does not have a het but for some reason all educational material on the matter and the one university study i have read on enigma call it dominant, i presume there is a reason for it?

Heterozygous is one copy of a gene, we mainly use it for recessive morphs, but if it was "het" Enigma, then it would have one copy of the Enigma gene. And Enigma is dominant, so the gene would be displayed in the phenotype. If it is not Enigma, it has no copies of the Enigma gene.

What ^ said haha

It's different from snow because it does not show varying degrees. It's there or it's not.

That's with line bred snows. Mack's are you have it or you don't. Just like Enigma.

I think when she said "varying degrees" for macks, it's because
one copy=mack snow
two copies = supersnow

Enigma is dominant, since one copy of the genotype shows in the phenotype, and mack snow is co-dominant due to the different genotypes being reflected in the phenotypes. Enigma may be an incomplete dominant, though. I think the jury is still out on that?

Thanks!

Most Enigmas are One copy Enigmas. So 50% are Enigma 50% not, acts just like a MS. so..
MS X non Mack = 50% MS, 50% non MS
OR
One copy Enigma X non Enigma = 50% Enigma, 50% non Enigma

Two copy Enigmas give 100% Enigmas like a SS. so...
SS X non Mack = 100% MS
OR
2 copy Enigma X non Enigma = 100% One copy Enigma

This may be true on paper, but there is no way to visually differentiate one-copy from two-copy enigma phenotypes.

I do not believe it is co-dominant.

 

[RampantReptiles]

You are exactly right Lillith. There is no visual difference between a one copy and 2 copy enigma.
Enigma is Dominant not co-dominant.

Co-dominant just means that, both the normal type and the allele in question are dominant at the same time. That is why we get MS. The gecko is displaying the normal type pattern and eyes, as well as the black and white from the SS/MS allele.

Dominant and Co-Dominant act the same on paper, the difference is the way in which they are displayed in the phenotype.
