Genetics Question

Take a Morph PK Albino and cross it with a Morph Sharp Albino and get?? 50% het Sharp and 50% het Kahl?

That breeding would produce normal looking boas that would be 100% double hets for both strains of albino. If you bred the offspring back to each other, you'd have a hard time deciphering which albino was which. With the additional probability of having a random albino gene in with a visual albino, I believe you'd have a hard time selling babies. I believe most people like to know exactly what they're getting. Hope this helps.

It does, thank you. Ultimately, I wanted to know if it's possible, in a few generations, to breed in the Sharp gene into an already existing PK albino morph and breed out the latter gene.

If that's your goal your best bet would likely be to take the dh offspring back to a non het producing 50% poss het and trying those on hets to see if they prove het Kahl if not then success you have the base morph not het Kahl.

I am sure others have tried crossing the two genotypes. If not, I am sure with all the new genetic strains on the market it would be a fun experiment to see if any new phenotypic variation would occur. I thought of it a few years back and the idea was "poo-pooed" by the very same people who were crossing everything under the sun to try to make the next new morph. Who knows, if the genes crossover during meiosis you could make something new! A leucistic boa? There are not many of these. You could be the first.

It's still Looked Upon as a Bad Idea did you read the post by Posted by: Amp at Sat Jun 4 09:47:54 2011

Kahl X Sharp Genetics Question

The Breeding between Kahl and Sharp was done years ago By Peter Kahl and Brian Sharp.

At that time is was proven No special Phenotype is produced by breeding these two together.

All that you produce are Double Heterozygous Boas they are Het for both Kahl and Sharp strain boas.

Once somebody were to breed those Double hets back together they
would not be able to pick out one from the other.

A Double Homozygous Kahl/Sharp Boa would most likely
Not be distinguishable either.

You would have to Keep all the other babies or cull all of them
because releasing them into the market would be a
huge problem waiting to happen.

Honestly think about it, what kind of chaotic disarray would ensue ???

Moving forward these offspring could have far reaching impact on future projects . . . . . mostly negative impact.

We see it happen now when people get a Boa thought to be an
Albino but they find out it is also het Anery.

With this combination most people are usually happy about
this hidden unknown gene.

In some situations people are not happy about it, it takes years
to raise a Boa to maturity.

Do you realize how upsetting and demoralizing it would be to
raise a fem Boa for 4-6 years only to find it turns out
Not to be what you purchased it as.

You wanted a sharp strain Boa to make Paradigms with and find out
it was a Kahl strain . . . . ut oh . . . now what ?????

I think a visiable PK and Sharp in the same animal will look very cool.

BNixon Jun 06, 2011 09:22 PM

I think what your mentioning Larry is someone selling some as het x and turns out to not be using your example.

There is a big difference in getting an extra het gene and it not being het at all.

It is possible through accurate record-keeping (registry?) to breed for Kahl albinos and, paradigms, albino paradigms, BW caramels, albino BW caramels (and whatever other genes you combine)to be all in the same litter. It's unlikely in my opinion that double homozygous albinos will be visibly noticeable from Kahl albinos, but the het Sharp-Kahl albinos may be brighter (het Sharps often have bright "normal" colors and yellowish bellies). Personally, I'm more interested to see if Russian T-positive to Kahl produces a "paradigm affect" since I've read you just get double hets with Sharps.
