hey every one I was woundering if someone could post some pics of a roswell boa and explan the genetics? I keep seeing talk about them and I dont know anything about them.

thank you and happy holldays

Hello good Question! I believe that the ROSWELL boa mutation seems to be a DOMINATE Trait due to the fact of extreme pattern and color, and the Ladder tails that come from the litter's of the ROSWELL's seem to be the Co-dominate trait of them. REMEMBER EVERYBODY just my opinion so don't get heated at my thoughts. Thanks,
PIC for your viewing pleasure,

Just a couple things. Firstly, that picture in the above post isn't a Roswell boa! Beautiful, but not a Roswell so to the OP don't get confused there. I thought that they were thinking Roswells were recessive though I'm not certain either. Dominant traits are traits where the mutant gene is dominant over wild type and visually appear the same whether homozygous or heterozygous. With codominant traits the mutant gene is dominant over wild-type as well, but there is a visual difference between the homozygous and heterozygous forms. Heterozygous and codominant are not synonyms though they are misused as such quite often.

The first thoughts were that the Roswell was a Recessive trait I think.
Although seeing the Laddertail versions many people believe the
Laddertails are the Heterozygous form of a CoDom trait.
The Roswell itself being the Homozygous version of the CoDom trait.
Below is a Link to a post made on a different forum .
There is a picture of the first Roswell produced.
You can also do a search of this forum and find posts
and pictures of the Roswell project.

The first Roswells showed up in my 2007 pairing of two 50% Suriname boas het for albino...the parents were siblings...

The litter had 13 live babies, which included this live male Roswell, and two stillborn siblings, that were striped the exact same way...

A few more pics of the 2007 male...

In late 2007, I paired the father of this litter, with his other, larger sister...she gave birth May of this year, there were 26 babies, and 6 Roswells...

Only two of the Roswells survived, one male and one female.

All the Roswells from this litter, especially the albinos, had large amounts of yolk in their bellies, and I think this may have directly contributed to their deaths. I am now outcrossing my adult trio to other, unrelated boas...I am hopeful the addition of new blood will make for stronger Roswells in the future...

The genetics are still unknown at this point, but I believe that the Roswells are a super form of the laddertails. All three adult siblings, have connected patterns, some degree of streched out side medallions/side striping, and laddertails. In both litters, a little more than half the babies strongly resembled their parents, with the remainder having 'classic' looking tails...

The larger adult female, is currently gravid by an unrelated 25% Suriname male...and due in early April. I am going to take a guess that the babies will be half laddertail...and I believe a laddertail male from this litter, bred back to the smaller adult female in the future, should produce more Roswell boas, if I am correct about the genetics...

Babies from both litters with connected patterns/laddertails:

And a few of their classic/normal tailed siblings:

My adult trio was produced in 2003 by Todd Smith and Dr. Bryan Wayne, from a Colombian albino X pure Suriname import female...according to Todd, the male albino had an ordinary appearance, but the female Suriname had the connected pattern and laddertail, and around half that 2003 litter were laddertail and resembled their mother...

Here are a few pics of the adult trio:

Male:

Smaller female: (mother of 2007 litter)

Larger female: (mother of May, 2008 litter)

Johnathan, Todd said the female passed in 2004.

It's really unfortunate that the import female is gone...if the gene originated with her, it would have been one of the few pure BCC genetic morphs out there...

Was just looking through my old emails, the number of babies from Todd's 2003 pairing that were laddertail, resembling their import Suriname mother, was closer to 75%, and not half, as I posted above.

Heather, Is it possible my 1.1 '06 50% Suriname Kahl Albinos from Todd Smith are from the same gene pool? He did have a partner on the ones I got.
Do you know anything about that? My male is super good looking with a perfect pattern. No laddertail, though.

Here is one of the three '06 66% pos. het. females I got in the deal. I sold this one. Sold another one just like it. Still have one more 66% poss het. female and the pair of albinos (both 50% Suriname). Kept that one female 66% pos. het. because something about her made me pretty sure she was a 100% het.
Got them from the same people, more than likely breeding at least some of the same Roswell stock. Just 3 years later.

This is the '06 male 50% Suriname from Todd Smith and partner.
I still have the individual I.D. papers from all 5 I got in the deal. Still own 3 of the 5.
This guy is special. There's a lot of orange to his yellow. Not your typical yellow Kahl Albino. Roswell step brother/half-brother/cousin???

That type and color of yellow Albino Boa I'd take that Boa any day
Like you say the yellow seems to have some orange influence absolutely beautiful.
That's just a smok'n hot Albino John !
