Anyone notice unexpectedly bad odds hitting visual/homozygous hypo from breedings involving at least one het? If so, does it seem biased towards being an issue from one particular gender of het hypo parent? Like het hypo sperm swim slower making it hard for a male het hypo to pass on hypo or female hets tend to ovulate fewer eggs getting hypo from them?
I’m on a four clutch streak of no hypo from het X het and thought it was just bad luck but a friend heard it might be a known issue. Really curious what would cause such an issue if it actually exists and if there is a gender you want to be locked down homozygous for hypo to get expected odds.

I would consider having the sheds tested to verify the het hypo.
I don’t think it’s an issue I’ve run across…Desert Ghost was the one that confused people for a bit.
There have been a few talks of lines of hypo that have been incompatible, but it seems like the other line is pretty rare. I haven’t heard of that issue in a long time… So it could possibly be that as well if both are from a visual parent.
What were they purchased as?
How large have the clutches been?
Het to het is generally a 1:4 chance, but that still can have bad odds in a small clutch.
It took 6 normals before I produced an albino in a het to het gecko clutch.
In a 4 egg clutch I managed 4 lessers from a het lesser.
My 2nd year breeding bps I paired 2 het hypos from the Orange Ghost line. 3:6 were hypo. Her last clutch was 2:7
My hypo female I purchased 2 years ago dropped 8 eggs and it was also an even 4:4 split.

Both sides of mine were tested het hypo (not born 100% hets). The male from three of the clutches I even tested with both providers to be sure. Could be bad luck but even with small clutches the odds are getting longer and longer on missing that much.

Oof. That’s really weird.
I would cry if I was in that situation.
As is I’m frustrated that for the second year I haven’t seen a male lock with any females… Not the same but still means I’m not getting the particular morph I want because of it.
Not sure how many breeders frequent these forums so I reached out directly to two US breeders I know and both reported making visual/homozygous hypos at expected rates from hatched 100% het hypos as was my pre-shed testing experience. I gather that the not US breeder group reporting what would appear to be terrible odds was also working with possible het hypos tested as hets like my more recent stretch of misses on homozygous hypo.
Would still love a lot more feedback from people breeding het hypos including if they were hatched as 100% hets or as possible hets upgraded to hets through testing. Not nearly enough data yet to make any conclusions.

I heard back from several more US breeders who also reported getting about the expected odds breeding hatched 100% het hypos (ie from a visual parent). A little surprised I was only able to find one other breeder using tested het hypos (ie hatched possible het but tested het). They also reported expected odds with no unexpected problems hitting visual/homozygous babies.
I haven’t yet been able to get any more details on what the Mexican breeders saw that lead them to believe it’s very difficult to make visuals from hets.
Not sure if I’ll do retests on any of mine that failed to prove. Maybe.
