Banana Girl? Is Banana Gene not jus for boys?

[Ronniex2]

So here is a very interesting topic and One that has been discussed for a long time. If you’re familiar with the banana gene, we all know that the bananas that are produced from those not”female maker”, will be boys.
In my experience… Especially reading too many forms… And through my own breedings, I have not had the fortune of hatching out a Visual Grill Banana
That was until the season… I have this beautiful purple snake that came out of this egg…
Mom (Xenia - Pied) would be more interesting than the Father (BP/Pastave/Banana), but her lineage is still to be determined- I got her from a friend… He had very limited information on her and her genes, but a visual pie female is always worth the investment
So I got her… sire was purchased from a reputable breeder and has sired four clutches for me
Out of the four classes I had gotten 12 bananas, all boys until now. Not entirely sure what the big difference is or if there is a big difference between coral glow and banana, but the odds of creating a girl banana again would not have great odds @ 11.1
Just asking if anyone has had any luck with creating a “Female Bananas” from a “non-female makers”
Also, if anyone can help me with what experience of these purples ? Cause she is on fire definitely the HB and her clutch mates are as follows
2.0- Banana/Pastel / Het Pied
1.0- Banana/Mojave / Het Pied
1.0- Pewter/ Het Pied - do we see banana?

Bananas and coral glows always have a very small chance to throw the opposite gender. That's how the original females happened since the first few generations were all males. It's just fairly rare. Garrick of Royal Constrictor Designs had a clutch where I think a male maker threw 2 females.

My banana and coral glows are all females at the moment, so I haven't gotten to play the maker game since they throw both sexes.
Over time as bananas and coral glows are crossed out, I wonder if maybe there's more chances to have the opposite sex hatch, but not 100% sure. It just seems like it's more of a common occurrence now than it used to be.



As for your little one, looks like a beautiful Mojave black pastel.

I think that there are just more banana ball pythons out there so more people breeding and reporting. For a male maker to sire a female banana, there has to be a crossover between the male's X and Y sex chromosomes. That swaps the piece of chromosome with the banana gene from the malemaker's Y chromosome to the X chromosome. And I am not aware of any mechanism that increases the number of crossovers.

OK totally understood… & thanks for the clarity
I have been doing some more research since then, and have noticed the same trend… That more people are having success with more females in clutches…
Also, I would say selective breeding as well as just by chance
I know that the odds are not great but jus wanted to see if anyone else has had success in less clutches versus to females if you know what I mean, jus really was blown away by this lil beauty … had no idea I’d be so lucky w/ her as she was the pretties of the clutch but she’s a she and I am jus happy with that … she’s also 100% Het pied so definitely something to look forward to
