All I have to ask is in the title, thank you in advance.
Okeetees are a line bred locality. Extreme okeetees are okeetees that are much more vibrant and have stronger colors. Reverse okeetee refers to an okeete that is also amel. The pairing would be extreme okeetee amel x okeetee amel. So you will end up with a clutch that is all reverse okeetee with slightly varying degrees of color and vibrancy.
You’ll get a variety of reverse okeetees, some looking more like the father and some looking more like the mother and some in between. They will all be reverse okeetees (genetically amels) unless there are some shared hets.
