Odds

For all practical purposes, the answer is no, but technically there are some very slight possibilities.

From what I remember of a college biology class, there is a chance that something in the co-dom's reproductive system isn't working properly, causing all or most of the sperm (in this case) to be normal sperm. Or maybe the co-dom sperm are made, but not made right, so they have less chance of fertilizing the eggs. It could also happen in reverse, so that only the codom gene gets passed on. I don't remember details, and it is possible I'm remembering it entirely wrong, but from what I remember, there is some way due to some sort of damaged chromosome or other reproductive malfunction, that a heterozygous animal can pass on only one of its 2 different genes.

I also believe the chances of this are about as big as having a new morph mutate spontaneously during one of your breedings. So while it is technically possible, but in reality we are unlikely to ever see it.

To answer your original question, as far as I know, there is NO chance that the female's normal genes overpower the male's codom genes. If the female had a different gene, it could possibly be dominant, but then it wouldn't be normal anymore. As far as I know, none of the known BP genes work this way, so it would have to be a new mutation, but it is theoretically possible.

Bottom line is that you are exceedingly unlikely to see this. If you are working with dinkers, it might increase the chances slightly, but for all practical purposes, the answer is no.

Just try again next year.
