Recessive: Het to Het bredding question

First I never bred pythons before, and I was reading a thread in another forum.
Some one stated that when breeding hets (for example: albino) that since ball pythons lays a small number of eggs, that you make not get a visual morph in the first breeding. And may take 2 or 3 breedings. Is this true?

Thanks to all that reply.

Yes that is very true you could get no visuals and you could get all visuals.

With het to het each egg has a 25% chance of producing a visual morph.

Hope this helps

Yes, het to het gives you a 1 in 4 chance (per egg) of seeing a visual morph. So a 3 in 4 chance you wont see one. Het to visual morph is 50% chance or 1 in 2. That is for recessive traits.

was this guy implying that het to het means that the first clutch ever will not produce any morphs?

no I think he was asking if there was a chance that you could breed het to het and still not get a morph.

Wow, that could be disappointing. And if you got no visuals you can't tell what percentage would be hets, you just know that its poss 50%.

So It would be better to get more than one female. Thanks for the info. I can make a better decision when it comes to the recessive traits.

Has anyone here bred to two recessive hets and didn't get any visuals?

Welcome to the world of breeding ball pythons AKA nerve racking at times lol.

Welcome to the world of punnet squares and recessive genetics. :D

Basically if you use a punnet square it's a lot easier to visually see what you've likely read but it comes down to this basically....

visual morph x visual morph - you get all visual morphs

visual morph x normal - you get all 100% hets (in other words all the normals MUST carry the recessive gene) but you will get no visual morphs from this mating

visual morph x 100% het - you should hopefully get some visuals and any normal will be a 100% het for the recessive gene

100% het x normal - you will get all normal appearing offspring with 50% carrying the recessive gene (statistically speaking)...so these are your 50% possible hets for that gene

100% het x 100% het - you will at some point get a visual morph from this type of mating (unless the BP Gods really hate you or you bought your 100% het from an unreliable source).....also some normal appearing offspring....the normals however can carry the gene or not carry it so statistically in a 4 egg clutch you could have 1 normal, 2 100% hets and 1 visual - these hets are your 66% possible hets for that gene

This is a great site for learning the basics of each type of genetics....

GREAT post Joanna! I know all about it but I must say you worded that really nice. It's really is easy to follow and to understand. Hopefully people will be able to read that and go "Ok... I see now... I understand". :)

Yes, when looking at some of the websites of breeders, you'll see them say that "missed on this clutch". It means there was potential to produce a visual, but none were produced. It also applies to co-dom breeding when hoping for a super form. I.E. pastel x pastel SHOULD in theory produce a super 25% of the time. But it doesn't always work that way. You could get none, one or all.
It's part of what makes ball python breeding great.
