Het Percentages

[mebigbadbrat]

Hi. I am wondering if someone can explain the Het percentages to me.
I get if a visual was breed to a normal you would get 100% right?

I have heard of 33%, 50%, 66% and 100%. I am just trying to make sure I understand correctly.
Thanks

visual X normal = 100% hets
visual X het = visuals and 100% hets
Het X het = visuals and 66% hets
het X non het = 50% hets
anything else in my opinion is a normal until a parent is proven as a het or homozygous.

What about if one parent is visible but gives you a 66%? I saw that some where in an ad and it didn't seem right to me.

Thank you for breaking it down.

I have a clown male and everything he breeds will be a 100% het, normals and morphs.

If one parent is visual you will always get 100%, as for the rest, what Jerry said = ).

That's what I had thought. I am going to see if I can find the ad real quick.

Never mind. I can't find it. =(

So is there a genetic het table for future breeding? Like a genetic wizard?

What if you were to breed two 66% together?
Ideally I guess you would want 100% hets if you get a het or at least a 66%.

If the two 66% snakes hatch a visual, then both become 100% hets.
But the chances are pretty slim. If you wanted to prove a 66% het, then it would be best to breed it to a visual. That way, all the babies are guaranteed to be at least 100% if none of them proved out.


But I wouldn't even bother buying a 66% het, unless they visually show some promising traits that the gene is there. (i.e. rail road track markings or ringers on het pieds. And many het clowns have a 'look' to them that isn't the norm)

Overall, it's just best to buy 100% hets or visuals. There's no guessing game or poor odds that way.

That would get very messy, besides the normal factors, when dealing with pos hets parents that don't prove out, another factor to add is the number of eggs laid, it a very variable thing, that in the end, really doesn't mean much. Your not going to be selling babies as 12% pos hets...

when dealing with expensive recessive morphs, you can see 33% and 25% being sold. 33% comes from a 66% het parent bred to a normal and a 25% comes from a 50% het parent bred to a normal. I doubt you will see it ball python world, unless we get a game changing recessive.

However you can turn on pos het ouput and it will tell you what % the babies will be when dealing with recessive het pairings.

Hmm. Here is what I am looking at: I currently have an albino (visible) male who I want to get a pied (visible) female for. I have found an excellent priced pied girl with low-med white who I love at 400-500 grams.

If I breed these two together, I will get the double het 100% albino and pied. Then this is where I am iffy. I could keep a male and female 100% het albino/pied to breed later on to try for that 1/16 chance of an albino pied but if I were to purchase a visible pied het albino or an albino het pied, then the chances are better. I mean it would take a few years to do either way.

Both the 400 gram pied and my albino could probably go next year. So maybe 3 years to 4 years to do if everything goes as planned. What do you guys think?

I think a 400 gram female won't go next year
