Suma x Banana =
1/2 Banana Mahogany
1/2 Mahogany
and then you are having to go another generation at least to hit Banana Suma
You would be better of starting with a Banana Mahogany male than just Mahogany male. Really think this through what your end goal is before you start and you will save a lot of money and time. If there is anything you want in super form or any recessive you are wanting, it's best if your prize male you breed has it though over having things you only need one copy of. So if you are trying to hit Banana Mahogany Clown for example, I would choose Clown Mahogany male > Banana Mahogany. You have more time to pick a male than a female because females need a lot longer to mature, and the longer you give your female to get nice and big, the more eggs you will get the first year.
