I've done selective breeding of various species of animals for over 40 years. It started with fish and birds in the 60's, then I began breeding dogs in the 70's, and added cats in the 80's. At first it was just a fascination with the circle of life, watching the newborns develop into juveniles and adults.
Once I started to competitively show my animals in the 70's, the obsession with manipulating the look of the animals set in. Do you know what guppies and bettas looked like in the 60's? I only remember two colors of bettas, red and blue. And they had rather limp fins. Now we have tie died looking fish with full moon fins. Parakeets in the 60's were either blue or green, Now you can get them in almost any color. Persian cats in the 60's had pointed faces, long bodies, and shaggy coats. Now they have Pekingese looking faces, short bull dog type bodies, and coats like a cloud of cotton candy.
Corn snakes are really in their infancy. Humans have been selectively breeding fish and birds for thousands of years. Dogs have only been competitively shown for a couple of hundred years and the Cat Fanciers Association just celebrated its 100th anniversary. The first man made morph of corn snake was born in 1961. We are basically in on the ground floor. How exciting is that?
My goal is to breed snakes that can reliably produce two colors, hot pink and royal purple. I've seen a couple of examples out there already, but they are still rare. Personally, I think too many people are focused on producing new morphs before they have set in the characteristics of their existing morphs. I think when a breeder charges big bucks for a hatchling, he/she should know what that hatchling is going to look like when it's an adult AND what it's offspring will look like. How would you feel if you paid a small fortune for a toy poodle and it grew up to look like a St. Bernard?
OK, soap box is stored back under sofa. Just my opinion...based on 40+ years of breeding animals.
