what would you get with a type II anery and a het anery.

Re: what would you get with?

If the het anery is Type I then you will get a litter of normal appearing boas all het for Type II, 50% of them also being het for Type I. Type I and Type II are not compatible so no anery boas will be produced.

If both boas are Type II then you will get a litter where 50% will be Type II anery and the other 50% will be normal appearing hets.

It is best not to breed the 2 different strains together, this would be like breeding a Sharp to a Kahl albino.

Re: what would you get with?

why is a type I and type II not compatible?

[emeraldtree]

Re: what would you get with?

what is the difference between the two?

[dangles]

Re: what would you get with?

it's like the kahl strain and sharp strains of albino. they just don't mix because they are on different locations (genetically speaking). one originated in a CA boa, and the other in a columbian boa (i think...)

type 2 central american type 1 columbian

I believe that is correct. I know the Type I strain has been claimed to have been found in different localities including Columbian and the type II is central American.

Like he said, they are on different locations on the snakes dna and you need 2 matching genes to make a recessive trait visible on a boa. If they are not on the same location then they cannot combine to form a pair. this is why we do a punnet square with pairs, you have to match compatible genes to get these recessive traits.

Re: what would you get with?

If you bought your het anery as just that a het anery, the chances are that it is Type I and not Type II. There are more Type I's on the market.

Re: what would you get with?

I am very lost right there with what is recessive and how you know what is compatible recessive traits and where dominant traits come in.

don't get discouraged... you are definitely not alone in that. genetics takes a while to get a good feel for most of the time.

in (very) short, there are several different gene types...

recessive
dominant

there's also co-dominant and incomplete dominant, but i don't wanna confuse you TOO much, so we'll stick with the basics for now...

for a particular trait, each offspring receives a gene from each parent (it takes two genes to make a trait).

if the trait is dominant, it only takes one gene for the trait to be visible. the hypo gene is a good example of this. all it takes is one hypo gene from one parent for the hypo gene to be visible.

if the trait is recessive, it takes the same gene from each parent (for a total of 2) to make the trait visible. the albino and anery genes are both examples of this. if the offspring receives a single albino gene from one parent, and a normal (also called "wild-type") gene from the other, the offspring will be heterozygous for albino, meaning, it only has one albino gene, and therefore, will not LOOK albino.

make sense?

Re: what would you get with?

So they way I am reading a type I and type II will not produce anerys. so with that wouldn't that particular snake be het for both type I and type II. Or what would that be they can breed together right just nothing will come of that?

[emeraldtree]

Re: what would you get with?

Yeah I under stand that dominant traits such as hypo or pastel or laddertail, Right? Put aren't those also co-dominant if paired with albino or anery. I guess what I have a hard time understanding is how we determine that. I am not sure what is a co-dominant trait and what is not. and similarly what is recessive. Technically isn't two recessive traits what determines double het/

Yes they can breed and have offspring but it is like I posted earlier, if you breed a type II homozygous to a het Type I then all the offspring will be het for the type II since that parent was homozygous for the trait. Half of the offspring would also be het for type I. All boas born will appear normal.

Laddertail isn't a genetic morph. Now there are different genes that have the laddertail look incorporated in them such as Key West Boas, Aztecs, Motleys, etc. but the ones that are referred to as laddertails are not genetic, it is just a wild type pattern anomaly.

Pastel isn't a genetic morph either, pastel is a selectively bred trait that is polygenetic, meaning there are many genes at play to make this type of "normal". You can't just breed a pastel to any normal and expect a certain percentage of pastels. Now the pastel appearance can be passed and enhance certain traits but this is no different than just breeding a dark colored boa into a project hoping to get some dark babies or a boa with abberent pattern or thin saddles.

A co-dominate trait or incomplete dominant is used to describe a trait that shows a visual form in a heterozygous animal. With the codominant traits you will see a "blending" if you will of the dominant wild type and this trait. It's like taking a white flower and mixing it with a red one to get pink ones. The pink ones are a mixture. Incomplete dominant will show up in the het form but the homozygous form may be more exaggerated or altogether different. This is seen in motleys and super motleys, super motleys are patternless dark boas, and Mojave ball pythons and super mojave where the super form is a leucistic animal and all white.

An animal that is het for 2 different recessive traits is called a double het. This is like when you have a het form hypo that is also het for albino, we call that a dh sunglow.

Edit: Breeding 2 different strains of a similar trait isn't a good idea. Just like with the 2 strains of albinos, it is hard to determine down the road what strain you have produced. You don't want to sell babies that are supposed to be sharp strain and they turn out to be kahls. This could ruin someone elses breeding project or future plans down the road. The anery types are a bit easier to distinguish but mixing may still be a bad idea, especially if the one purchasing them or breeding them doesn't know that much about genetics. You get the same result as with the albinos, and possibly an upset customer if a breeding season or two is derailed because they got the wrong type.

I hope this helps some.

Re: what would you get with?

That most definitely cleared up alot. Accept I didn't think there was a het hypo. I thought that in order to be hypo, it would be visual. But as goes for the breeding two different strain of the same, like with type I and type II, i guess my question is why hasn't this be explored. Now this goes off topic, butI once did a project in school over some people located in southern Turkey. They were called the hand walkers for the exactly what it is, they walked on there hands. They believed that the reason why they did was a result in two of the same incomplete genes from two different people. This resulted in the reason why they walked on there hands. What I am saying is that if you take homozygous type I breed to a homozygous type II, and get normals. They should be het for type I and het for type II. Now what would happen say you bred that to another het for both. What do you get??
