Boy, haven't been here in a good long time...

Anyway, I was wondering if all the traits are recesive in cresties. Like, what colors, patterns, etc are recesive? Which one, male of female, determines the color/pattern?

Just an example, if you had a male red harlequin, and a female orange bicolor, would the colors/patterns kinda go together or would one be more prevelant in the offsrping?

Wow I'm confusing myself lol. Anyone understand what I'm trying to say? I'll try to make it more simple if you guys cant understand, its hard to put out in writing.

i think most people agree that because of a lack of much genetic research on ciliatus that most traits arent simple recessive or dominant. as far as i know, you cant really tell for sure what babies will look like when you cross two different colors or morphs, you might get some that look like mom, some that look like dad, maybe some that look like neither really. and as far as breeding the same morphs together, maybe someone else can clear this up but i think even there you might get offspring that dont totally resemble mom and dad.

It's not quite that simple, but I'm sure there are simple recessive and co-dominant traits. It's just that there hasn't been enough research done to find out what they are, which ones are independent of eachother and which ones, if any, are connected.

I do have my suspicions on a few of the more simple traits, though. For instance, the dalmatian trait is fairly straight forward trait to identify (it's either a dalmatian or it's not). I can't speak for anyone else's dalmatians, but the line I work with (listed as the "Bawaa Herps/German line" on my site) seems to be co-dominant.

I say that because when breeding two dalmatians together, I've noticed the following ratios have been consistently as follows...

25% have no spots, meaning they don't appear to carry the trait.

50% have a few dalmatian spots...meaning they're heterozygous carriers of the trait.

25% have a relatively high number of dalmatian spots, meaning they're homozygous for the trait.

When breeding one of those dalmatians (the ones that I'd call heterozygous), I get about 50% spotted babies and 50% non-spotted babies...and zero of the really heavy spotted ones.

All of that points toward co-dominant genetics, but I can't say that definitively because I've only worked with two generations of that line and there simply aren't enough animals in the group for me to be able to say for sure just yet.

As for color, that seems to be totally independent of pattern and to be completely independent of pattern. There's a whole page about color on my website, so you might want to look at that.

No animal that I'm aware of inherits a trait (pattern or coloration) specifically from the mother or father.

It will likely be a long process though.

I am recently new to contributing to this forum, and only got my first crested last sept, I currntly just bought my fourth crested gecko (not new to reptiles or their care keep in mind)

breeding now is a harlequin male to a orange tiger female.
in july i will add my new harlequin female to the group (after 1 year old and at least 35ish grams) - Thanks Randy!
one year from now i will add my partial pinstripe to the mix (sex unknown) - Thanks Anthony!

so there is a decent mix in there, in about a year o so i will compile my findings and add them to the forums. hopefully it will help shed some light... maybe a little.

My plan is to keep track of who "gets" with who and plot out the ratio of different genetics represented. I think it would be awsome for others to start doing this if they find it interesting. I understand that for many of you there is alot of ambiguity as to wich animals are breeding wich at some times. But still, if you have anything to contribute i know i will be interested. Many of you are years ahead of my in regards to the production of offspring and so im sure there are a few of you who see this in action alot more than many of us.
any other thoughts?

Wouldn't this just be sooooo much easier if they laid more than just two eggs! Four would be nice.
