Those defects you listed were all from morph inbreeding.

Many captive snakes have a large enough population not to need new WC blood. Just like stated with the island, a population can start up from very little original blood. Captive populations undergo new mutations just as they would in the wild and as they are bred new genes will randomly appear. These gene changes are not represented in wild snakes so the captive breeds will be slightly different. Additionally, rare genes could have been present in the WC snakes that started lineages. These genes will now represent a larger portion in captivity than in the wild. In captivity, brighter colors are usually selected for. We select for different genes than nature does.
