Super Coral Glow - male or female maker?

[Kroberts10]

The best way I can describe it on the more genetic level. Is that the gene for the banana color allele is found on the sex chromosomes. On a female it doesn't do the sex ratio thing since there are 2 X chromosomes and it doesn't matter which chromosome the gene is on. It works with males since there is only one of each. And if the male banana gets its gene from its mother, then the gene for banana is on its X chromosome. So any time the male sends an X chromosome making a female baby, it'll carry the banana gene with it. Where as sending a Y chromosome won't have the gene. Making a female maker. the same is true for the male side of the equation.
The reason for the random male or female banana where it shouldn't be, is due to crossover. Where during mitosis or meiosis, genes get swapped from one chromosome to another, swapping the banana gene from the X to the Y chromosome in a female maker, giving you that random male. The super form of the banana has a gene for the banana allele of both the X and Y chromosome, so all male and female with show as banana.

I hope this makes sense. And helps some.
