I found this very interesting

Just goes to show you never really know what your going to get

Wow, that's just insane. Really cool how nature will give science a big "screw you" every once in awhile.

Such chromosomes are passed on to following generations just like normal chromosomes. But the action of the deleted gene or genes no longer happens.

so if im understanding this correctly, the punnet squares above would apply to this right? or does it not pass to the next generation like that?

Maybe I'm missing something, but isn't possible that the the "normal" female is a really normal looking new variant of the BEL complex? In which case we'd also say that the clutch hit bad odds in that 50% weren't BELs.

I understand the other explanation that the null phenomenon may have occurred in this baby, but then one would have to assume that the mutation occurred very early in development for the snake to be completely affected, and not look like a paradox. It will be interesting to breed it out, but one has to keep in mind that the mutation may not necessarily be expressed in all the cells of the snake, such as in the reproductive cells. Very cool stuff.

its all theory right now, it's possible anything could of happened. but for the variant that looks normal to act exactly like mojave when paired up to another mojave? also the odds would be 25%

the current theory on paradox is that twins early in development merge into one snake, and it makes sense with how random but yet how often it happens. supposedly if you take dna from one part and dna from the other different part of the snake, the dna will show as siblings, not the same snake. This has been documented in other animals, call chimeras. This has nothing to do with what we are seeing in this thread.

we will be stuck waiting on more info, for now we gossip and theorize.

If there has been a deletion, it probably occurred when the egg cell was developing in the mother, before the egg cell was fertilized. Then the deletion would be in all of the baby snake's cells.

The Punnett squares in post 29 apply. Just change the word "null" to "deletion"
