    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....

what means poss. het 66% amelanistic, 66% hypo and 66% anery exactly?

tangerine poss. het 66% amelanistic, 66% hypo and 66% anery x tangerine poss. het 66% amelanistic, 66% hypo and 66% anery

tangerine poss. het 66% amelanistic, 66% hypo and 66% anery x albino

Resultat ?

Snake is Lampro. trian. hondurensis

It means every snake from a het to het pairing has a 66% possible chance of being het for the recessive mutation in question.

Example:

het Albino (1 allele) x het Albino (1 allele)
=
Albino (2 alleles)
&
Normals 66% possible het (1 allele) Albino
offspring

66% het is used because statistically 66% of the normal offspring should be het for the recessive mutation.

75% of a clutch from a het to het pairing will be normal
50% of that 75% will carry the recessive allele
divide 50%/75%
equaling your statistical chances
 
Also,

tangerine 66% amelanistic, 66% hypo and 66% anery x tangerine 66% amelanistic, 66% hypo and 66% anery

Would show you if any of the snakes are actually carrying the same genes (amel, hypo & anery). If when paired, they produce one of them, that proves that they are hets for one or more of the mutations.

tangerine 66% amelanistic, 66% hypo and 66% anery x albino

This pairing would be another way to test for Amel in the 66% individual.
 
Dirk, I know that our site is hosted for free, but I've got a breakdown of genetics on there that is quite understandable and workable as a starting point for further understanding. The site URL is http://double-d-reptiles.tripod.com/genetics.html (may have to cut & paste to get it to work) and about 5 years ago was the only listed online resource for discussing animal genetics in a mid-high level textbook here in the US, so can't be too terribly bad. It was based upon corn snake basics as we were working with them much more at that time and needs a lot of updating using a second, more advanced genetics page but I haven't had enough time these past 2 or 3 years to do it correctly and there are a couple of other things that I'd rather take care of first. Hope this helps.
