Reptile & Amphibian Forums

I posted a question about a week ago and I guess I wasn't clear. What would a boa look like if it was double recessive for both sharp and kahl albino? Would it look any different than other albinos? Is anyone working on this combo? Thank you for any replies.

When you breed a Kahl albino to a Sharp albino , you will get offspring that is Het. for both traits. This offspring will appear normal with no albino traits from either strain. When you breed those siblings. together you should theoretically get

6.25% Wild Type (het for nothing)
12.5% Het. sharp albino,
6.25% Homozygous sharp albino,
12.5% Het. khal albino,
25% Het. khal albino, Het. sharp albino,
12.5% Het. khal albino, Homozygous sharp albino,
6.25% Homozygous khal albino,
12.5% Homozygous khal albino, Het. sharp albino,
6.25% Homozygous khal albino, Homozygous sharp albino, (or 1/16th)

The real question is what will that "6.25% Homozygous khal albino, Homozygous sharp albino" look like? Is it assumed that these offspring will fall somewhere between the looks of a Khal and a sharp albino? Or will these genetics produce something unusual to either strain of T-positive albino's. I know someone out there has to be working on this project, but might want to keep the results private.

i agree, i believe that there are people working on this combo, so morethan likely your chances of getting people to talk about their secret projects are slim to none

That was exactly my question, what would the snake look like if it was double recessive for both kahl and sharp strain albinos. Thanks for the reply

While I for one would love to see the results. There is a huge risk factor involved. Many of the babies produced could have undistinguishable morph status w/out breeding trials to prove them out. While there are differences between the Kahl and Sharp strains. The line between them is not 100% clear. So if you had a pile of "albinos" from the cross, how would you say what they were?

From a marketing standpoint, Unless you were working both strains, would you want to purchase a baby that may be homozygous Kahl OR Sharp and possible het for the other? Even worse, normal 66% het Kahl and 66% het Sharp.

Now, if the double homozygous animal does have a unique look, then it would be very valuable and a new sought after morph but then again, how to reproduce without inbreeding if the offspring were not distinguishable. The only sure fire method would be crossing double homozygous parents to create 100% double homozygous babies. It would be difficult to create two unrelated (not inbred) adults for breeding and even if you did, then how to make additional generations without inbreeding?

Wow, the more I think of it, could make MANY (and I do mean MANY) babies that were questionable morph status which could only be proven by breeding.

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

lots.lots.lots feeder mice and rats

yes , you are right we would have a bunch of "I have no clue" strain albinos for sale. And even more "I have no clue" hets for something or two things. It might be a marketing nightmare unless the double homozygous for both strain animals were something special... Then people might be willing to take a chance on the "who knows what they are" animals

Inbreeding is usually a part of creating a snake that exhibits the visual characteristics of two or more recessive traits. As in the snows, blizzards, etc. Unless people do a swap with their F1's. As in , your double het. normal appearing boas for mine, which probably will not happen.

We just hope that fresh blood is introduced after the desired snake is produced.

BTW heathn, it's not "double recessive for sharp and khal" but rather Double het. for the recessive traits sharp and khal. Sorry, I know it's a minor distinction .

Thanks,
Chris

I just got home from a 12 hour shift so this may not sound right. For the animal to show the kahl strain and sharp strain albino gene then the animal must be homozygous for both strains, what I meant when I said "double recessive". If it was just heterozygous then the snake would look normal. Please correct me if I'm wrong, like I said I just worked a 12 hour night shift and am very sleepy. Thanks for all the input, anymore discussion would be great!

Yes, I'm sorry.. You meant "double recessive" as Homozygous for both strains. That makes sense, and is the exact question I asked last week.

Another question would be, has there ever been a snake/reptile with two incompatible strains of T-positive albinoism, that have been bred to the point of producing an animal homozygous for both. If yes, what were the results? I know the albino diamond back rattle snake has two incompatible forms of T-positive albinoism. And maybe a few others? Or is that a secret too???

Chris

It is a secret I would like to know, but I've spent enough on snakes this year. So my fiance tells me, lol!

I've got one of those.. She has cut me off too.

I know I should start a new topic, but whatever happened to the type II Anerythristic? Last year I would see them in the classifieds on a fairly frequent basis. Now I see very few for sale, or posted on the forum. I wonder if the blizzard project didn't go as expected. I don't see that morph being promoted anymore. I don't think one has been produced yet? For those that don't know the blizzard was an effort to reduce or eliminate the yellow in a snow boa. Or at least I think it was.

Oh well, Probably another secret to add to the list.
