I have about 3 dozen feeder guppies. Today I bought a fancy male guppy to breed to my feeder females to increase the hardiness of the fancy line. Most of my feeder females are standard oil-grey color. Does anyone know of guppy genetics? Will breeding the feeders to the fancy improve their hardiness? How many generations will it take? How would I go able keeping the looks of the fancy? Does anyone know about guppy genetics? I know that to keep the fancy guppies coloration going I have to do "some" inbreeding. Maybe like great grandfather to great grand daughter?
