What I am curious about is whether two related organisms that have different patterns of sex chromosomes would even be able to produce viable offspring. I'd really like to see what sexes a male burm female ball breeding would produce because that would answer the question.

I apologize if that has already happened and I'm just not aware. Please let me know if it has.

The rate of crossover required for the banana gene to follow that mode of inheritance is another good point. I'm just going to shut up now so I don't seem as stupid to the people who know what's going on here...

Just out of curiosity do you know the underlying principles behind the inheritance patterns of the banana gene?
I dont believe a male burm to a female ball would work out due to the possible size and quantity of eggs. Similar to how a chihuahua can breed a great dane but the smaller dog (chihuahua) has to be the male.

No worries about the mixup. Nobody understands whats going on with it so we're all looking for explanations.
