Just curious about something I've seen in the classifieds... it actually has to do with BRBs.
In Columbian boas, hypo breedings will beget hypos or normals (or supers depending on parents) right? There is no het for hypo, or as someone theorized in a thread awhile back, the hets for hypo are the hypos themselves. Same difference of course ;p However, here is where my question comes in... does that mean there are or are not het for hypos in other species? I saw het or poss. hets for hypo BRBs in the 'other boa' classifieds and thought I'd ask the experts to explain why it is different...
It's probably very simple to understand, but I am afraid I really know next to nothing about BRB morphology...
Thanks!

Hypo BRB's are a recessive gene like ball pythons too. So in het. form it is carrier unlike the bci morph which is dominant. Here's a couple of hypo brb pics for your troubles

hope it helps

You beat me....and threw in pics..... take this

Dottie

and Dumbo

and Mickey

Hmmmm, I need more pics of Mickey......where is that camera?

LOL, to many snakes to list, last count:
24.36 BRB
19.19 BCI
And those are only the breeders

lots.lots.lots feeder mice and rats

me I'm about to send you some mail in a sec now go back to work

OOUUU OOOUUUU, where's the KS sensor, Bob's swearing again, he used that four letter "W" word again!!!!

Hey Steph, In BRB's Hypo is a recessive trait, Therefore a het or pos het hypo is possible and will look like a normal.

And yes, hypo in BCI is a dominant trait and yes there are BCI's that are het for hypo. Difference being they show the trait. Het simply stated is two different genes within one specified gene pair.

I really appreciate the replies, I figured it was something that could be answered simply, but it is confusing how the traits/genetics are so different, and yet similar, amongst the varying species.
Thanks!

ps- by the way, your snakes are gorgeous, both of you! So stop fighting! LOL!

>it is confusing how the traits/genetics are so different, and yet similar, amongst the varying species.

Yes. People look at a mutant trait in one species and apply the same name to a similar trait in both the same and other species. Look at all the "tyrosinase positive albinos" in boa constrictors. It would be easier if each mutant had a unique name, at least within a species. That is one of the reasons I prefer "salmon" to "hypo" for the boa constrictor mutant.
