Hello!
Either you have not registered on this site yet, or you are registered but have not logged in. In either case, you will not be able to use the full functionality of this site until you have registered, and then logged in after your registration has been approved.
Registration is FREE, so please register so you can participate instead of remaining a lurker....
Please note that the information requested during registration will be used to determine your legitimacy as a participant of this site. As such, any information you provide that is determined to be false, inaccurate, misleading, or highly suspicious will result in your registration being rejected. This is designed to try to discourage as much as possible those spammers and scammers that tend to plague sites of this nature, to the detriment of all the legitimate members trying to enjoy the features this site provides for them.
Of particular importance is the REQUIREMENT that you provide your REAL full name upon registering. Sorry, but this is not like other sites where anonymity is more the rule.
Also your TRUE location is important. If the location you enter in your profile field does not match the location of your registration IP address, then your registration will be rejected. As such, I strongly urge registrants to avoid using a VPN service to register, as they are often used by spammers and scammers, and as such will be blocked when discovered when auditing new registrations.
Sorry about all these hoops to jump through, but I am quite serious about blocking spammers and scammers at the gate on this site and am doing the very best that I can to that effect. Trust me, I would rather be doing more interesting things with my time, and wouldn't be making this effort if I didn't think it was worthwhile.

WOW, after re reading my explanation, I can understand the head aches inflicted. LOL Borderline manic on second look.
Here's where it was explained to me at Fauna.

It's better than I can put it, and by smarter people too.

First understand that Dominant, Codominant and Recessive are describing a relationship between a gene pair at any given locus on a chromosome.

A chromosome is a tightly wound strand of DNA. Although a chromosome is microscopic in size if you unraveled the DNA strand it would be about nine feet long.
Locus is Latin for "place." So, a locus is the physical place on this DNA strand where the individual genes are located.
A gene is a DNA "word" or code made up of four letters...G A T & C. It is a combination of these four letters that make the DNA strand. You can think of DNA as looking like this..
ATCGGCTAGCGT CAGCTAGCTAGGGCTAGGCTTG CTCGATCGTAGCTAGCT and on and on. The code between the bold C's could be a code for a mutant gene...lets say the salmon gene. And the place on this strand of DNA where this gene is at is called its locus.

Same with a Salmon to Salmon. They both have a WT gene that they also can pass on. Luck of the draw which gets passed on to who. LOL

WT=Wild type. A WT gene is a normal gene.
An allele is the matching gene located at the same locus on a matching chromosome. You inherit individual chromosomes from each parent. These individual chromosomes are called homolog chromosomes. Homologs combine to form homologous chromosomes. homologous chromosomes contain the same genetic loci in the same order. So, you have two sets of DNA. one from Dad and one from Mom. A allele is the gene on the other stand of DNA located at the same locus of its sister strand.

I think I'm only het geek. But I'm pretty sure I'm homozygous super stupid and codominant ugly.

Gaaawd Im glad my brain doesnt download that mess ......
I would be forever trying to understand all that crap.
I some how cant bring myself to a point where all that is important enough to invest my time understanding
Been over 30 years since I was book taught anything,building fast Chevys and working to fund such projects never involved genetics

You should visit those sites I posted Eric. Reading it from different peoples wording helped me out a lot.
That's OK Mark, I probably deserve it anyway. Happy New Year back at you.

I wasn't really trying to teach anything by that post. I was just mess'en with Rick and being a old smart @ss. You can't really learn this stuff on a forum anyway. If your interested in this stuff Eric you need to start with Serpwidgets cornsnake morph guide. It's filled with the right info. Here is the link....

Hmmm I'm still trying to wrap my miniscule brain around this stuff. I am starting to understand it... taking a while.
Basically, what I got out of it so far is that a co-dom would show traits of both. A Salmon would be concidered a dominant because it is either a salmon or it isn't... there is no het for salmon.
Could someone list some co-doms and some dominants? I pretty much have recessives down... Albino, Anery... stuff like that...
Now a Motley was called a co-dom at one point, but wouldnt that be a dominant also? If i am thinking correctly you breed a Motley to a WT, you get one or the other... so its basically the same in my head... it either is a motley or it isnt.. Thats what my head is trying to sort through... there is a super form of a motley, jsut like there is a Super form of Salmon... you jsut cant tell a salmon as being super or not until you breed... Is that what makes it a dominant rather than a Co-dom? because you CANT tell the difference between the Super and the Salmon?
Also, another thing that has been bugging me... I see adds for "Dominant Ghosts" in adds... If I am correct, a Ghost is a Hypo/Anery mis... If Anry is a Recessive trait, how do you get a Dominant Ghost out of it? Dominant to me is if you breed it to a normal, you will get all or none.. But if the Anery gene is a recessive, how do you get a ghost if bred to a normal?
Ok.... Lost again....
