    Yeah, I know. They are a pain in the butt. But they pay the bills to keep my server running. Just a fact of life, I am afraid.

    Want to get rid of them? Simple. Just become a Contributor level member or above and they will be gone. -> Please click HERE."

    Is that too much for me to ask of you to keep this site running? Well, sorry about that. I too wish I could get everything for free. But alas.....

    =====================


    Google Adsense ad revenue for December, 2025 was just $30 over the cost of the lease for the server running this site. So, in effect, the money providing the incentive for me to continue running this site is coming SOLELY from the paid memberships and sponsorships here. Which honestly ain't much....

Question...

Hi Dan,
Welcome to ball pythons. This is going to get sloppy and potentially confusing really quick, so I might simplify it a little. For this example I'll identify a male and female though I might have it reverse since you didn't specify.
There are 3 types of ball pythons:
1. Visual
2. 100% het.
3. Possible het. (any percentage less than 100% is basically worthless for calculations or labeling purposes*)
Either an animal is het. OR it is not. So... you need to calculate under two different assumptions, the father is het OR he is not, toss out %s <100%.

Male: Pied 100% het Albino
Female: 100% het Albino, 100% het Pied.
If he is 100% het Albino, you 'pretend' the ratios are something like:

12.5% 1/8 Het Piebald
12.5% 1/8 Piebald
25% 1/4 Double Het Albino Piebald
12.5% 1/8 Albino Het Piebald
25% 1/4 Piebald Het Albino
12.5% 1/8 Albino Piebald


Male: Pied (not het. at all)
Female: 100% het Albino, 100% het Pied.
If he is not het Albino, you 'pretend' the ratios are something like:

25% 1/4 Het Piebald
25% 1/4 Piebald
25% 1/4 Double Het Piebald Albino
25% 1/4 Piebald Het Albino


*odds truly are so unpredictable dealing with het. animals, especially double het that it is honestly futile to calculate or try to guess.
 
Thanks
