double recess. x double recess. but diff. morph
What exactly will happen if you cross two different morphs that are double reccesive? Is this where co-dom and dom. traits fall into consideration?
Re: double recess. x double recess. but diff. morph
co-dom amd dom traits are different than recessive. if you crossed 2 different morphs like albinoxpied you would get normal looking babies that are double het for the albino,pied morph. you then have to raise up the babies and line breed them to hopefully produce the albino pied. you have roughly a 1 in 16 chance to produce that, along with pieds and albinos and hets. check out the search feature here there are some threads on this already.

Thanks, thought I read most of it, maybe I missed something:oops:

Recessive, Codom, dominant (along with others which would really confuse things x-linked blah blah blah) are basically way to describe how the genes show up in the offspring. Each trait (gene) is given a name, ie. albino, pied whatever. Then (once proven) it is also described in terms of inheritablilty (recessive, codom, dom). In general, one gene does not affect another. That is why when you are looking at those punnet squares, you focus only on the one particular trait. If you are interested in more that one trait, then you have to widen your focus.
Did that help at all, or did I make it worse? :oops:
Re: double recess. x double recess. but diff. morph
No, it makes perfect sense..really:) I guess I was wondering if you have a morph with a double reccesivce gene say (aann) and you breed it with another double recessive (aahh) would the little aa in the offspring be dominant and show up in the offspring with the little n and h being the Het. genes? Wouldn't you get something like:
aanh?

If you take a double recessive like caramel hypos, aka caramel glows (gotta use examples I love ;) ) and cross it with a pied clown (just pulling that one outta my head), then you would get nothing but hets. The traits don't change from being recessive to being dominant. If you had caramel hypos and hypo pieds then you'd have eggs that had a 25% chance of being a hypo. The caramel and pied genes would not be expressed.
I think maybe you are just asking if the one trait would show up in an obvious, visual form. And yes, if you have both aa then whatever trait aa is would be expressed in the animal. The nh part would only be het for that trait.
The use of the word dominant doesn't mean it's expressed. It's how the gene behaves in a theoretical sense.
I'm sorry. I don't know why my poor brain is trying to do this in the am. It's not even awake yet. sheesh. *sigh* Maybe that helped, and would someone please put me back in bed. :please:

That is exactly what I thought, and glad you answered it. :sweeet:

Ha, I tried understanding double hets in The Complete Ball Python book by Kevin McCurley and I got more confused - mainly because in his example the caramel albino was designated with ccGG and the Ghost was designated with CCgg (I guess I was thinking that the capital letters should be opposite). My head started spinning so I put it down to try another day! LOL
Really need to understand it too, because I think a hypo clown would be awesome!
Re: double recess. x double recess. but diff. morph
I think that reference to caramel albino is just another name for caramel (hence the cc). Caramel is another form (T+) of albinism, and since it's has normal genes in place of the ghost you get GG. And the the ghost genes are gg and it's normal in the caramel locus you get CC. Using the small letters, since they are both recessives.
