I would like to ask all of your help to learn which combos in the 8-Ball complex have an increased chance for birth defects.
So far I am aware of Super Cinnamon and Super Black Pastel: chance of duckbill, rare chance of kinking.
Are there other known combos or supers producing defects?
Back when I made that list, I got data from bigger producers, biggest data point being 4 kinked animals out of over 40 supers. That’s about as rare as the reported data of getting a female from a male maker banana. Which we also call rare.
I also noticed anecdotal evidence that some people never/hardly seem to have issues and other have a high ratio of it. Seems the particular animals seem to play a factor and not just the cinny/BP gene exclusively. Ive noticed the same with super lessers and bug eyes.
That’s 10 percent I wouldn’t say that’s rare in my opinion.
I don’t know if I honestly believe them especially when bigger well know breeders are moving away from these pairings.
I’ll admit though i am a bit biased based on my own experiences with super black pastel and super cinny, which the pairings where multiple different animals(of both sexes) with multiple origins. And all were unrelated as well.
Most of the data was from the bigger breeders at the time.
Unrelated pairings is a toss up. I can’t speak for the 8 ball complex but with super lessers, I had 1.2 lessers (1.1 related) that never threw a bug eye’d BEL for 3+ years of breeding them. Then the male was replaced with a bel (related) and still, no bug eyed babies. On the other hand there people who mostly throw bugged eye’d ones with unrelated animals. Some claim the same with 8 ball stuff. again anecdotal and yes small sample size. But you can see trends.
One of those female last year I paired to an unrelated male, made 1 bel that had slight bug eyes. So I won’t be repeating that pairing again.
