Banana Hets and Sex Linking

I have a question regarding how the Banana sex linking plays out when working with Banana hets. Lets say for example that you breed a Banana Het Pied Male to a Visual Pied Female, lets say that the Banana het Pied is a male maker. Can you expect all of the offspring to be male, or just the banana co-dom offspring to be male? Thanks in advance.

Anything banana would be male. Unless you're lucky enough to hit that 6% or so chance of a female.

If you have a male maker all the offspring carrying the banana gene will be males while the non banana offsprings will be females (of course there are some exception every now and then)

If you have a female maker all the offspring carrying the banana gene will be females while the non banana offsprings will be males (of course there are some exception every now and then)

If you have a female banana het pied you will get an equal sex ratio and the males produced will be female makers.

Male-maker Banana Het Pied Male mated to Pied Female is expected to produce
~22% Male-maker Banana Pied Male
~22% Male-maker Banana Het Pied Male
~3% Banana Pied Female
~3% Banana Het Pied Female
~22% Pied Female
~22% Het Pied Female
~3% Pied Male
~3% Het Pied Male

The percentages are what I would expect, if that 6% chance of a banana female is correct. What a breeder gets could be considerably different simply from the luck of the draw.

The above works out to 1/2 bananas (mostly male) and 1/2 non-bananas (mostly female). 1/2 of all the babies are expected to be pied and 1/2 non-pied. Female bananas and male non-bananas are the result of the X and Y sex chromosomes swapping the region where the banana gene is located during the process of making the sperm. The pied gene is not in the sex chromosomes. Hope this helps.

When did sex linking become a thing with the banana gene? I dont remember this being discussed when I started almost 10 years ago, I've been out of the loop a bit though.

Thank you for the responses, makes complete sense.

Herpers have discussed banana being sex linked for several years, but the paper is only a year old. See https://www.researchgate.net/publica...Boa_and_Python

I read through the research paper, and found only discussion of X-Y vs Z-W, no discussion of sex-linking based upon visual mutation.

Looking through breeding records, it looks like my banana pastel enchi is a male maker.

So does that mean those males are also male makers?

It's been a known thing with banana/coral glows for a while, blogs and forum posts since 2011 or possibly earlier. (probably earlier since it's been around since 2002 but some of the forums are no longer active/up)
