Very new at this!

Hi all, can anyone give me a site that describes bp color genetics (like for dummies)? We are in no hurry to breed and want to learn as much as we can prior. Example, we bought a male 50% het for piebald. I have a basic knowledge of genetics (through canine studies) and understand pugnett squares but the 50% het throws me off. Does the breeder mean in more simple terms "recessive for piebald"? As in if I breed this 50% het male to a 50% het female I could potentially get 25% homozygous for piebald? I've seen other percentages that seem wacky like 66% etc,etc. Basically I need a good article or book. Any help for this newbie would be greatly appreciated.
BTW, Angus is doing very well - eating a full grown mouse every five or six days.

By breeding a 50% possible het to a 50% possible het you could be able to produce a Pied, of course you would need to be very lucky since your hets might be hets (50% chance) or might just be normals (50%)

50% possible het piebald is the result of breeding an 100% het piebald to a normal
Your het has 50% chance to be het for piebald and 50% chance to be a normal

here is a site that might make it simple to understand http://www.ballpython.ca/genetics.html

yeah it's simple recessive. this site is very informative for that sort of thing:

here is a great site with morphs. under the main menu is a link called "Ball Pythons" a drop down menu will will have alot of links and one for morphs. it is a great read
The Snake Keepers

and here are some links to some great reads.
Breeding
Genetics

hope this helps

Ok I get it now. I'm not used to that manner of phrasing so to speak. Makes sense now, thanks guys.

The Piebald/Pied Ball gene is recessive just because of the type of gene it is, it is not called recessive because it's 50% het.

In this example, your ball python is '100% het' or 'not het'. When a pied ball is bred to a normal you will mathmatically get half that are '100% het' and half that are 'not het', but you can't visually tell which is which, that all look normal. So if you reach in and pick one of them up, that one is 50% likely to be 100% het. So, it's called 50% het.

So, your pied ball is either 100% het or not het at all. The only way to tell is through breeding trials in the future.

Hopefully that helps a little...

Are you saying if you breed a visually pied ball to a normal you will get half that ARE het and half that are not het?


I was under the impression that since a visually pied ball has 2 genes for the pied that when bred with a normal ALL of there offspring will be 100% het for pied and obviously not showing just looking like a normal.

Its when you breed one of the 100% het pieds to a normal that the offspring are 50% het because some will be 100% het and some will be normal there by making the percentage of 50%. But there is no way to tell who is het and who isn't visually... only breeding them out over time will tell.

When sisco says a pied ball is bred...he means a 100% het pied. I had to go back and re-read it to realize that too. But yes you are correct. a visual recessive morph bred to a normal will yield all 100% hets. 2 100% hets will yield 66% hets. a 100% het to a normal will yield 50% hets.

As someone already said, they say 66% and 50% etc...to say that a certain percentage of that clutch is 100% het for whatever gene you are breeding.

Thank you for clearing that up for me. I posted a reply as I was heading out the door and I proof read for typos, but I guess I should have stated that better. I just returned home & I would edit it, but I don't have that feature.
