Its a fact morphs usually don't survive in the wild. there are those lucky few that do much the most don't. I mean do you walk out side an see albino animals every where? Its not that common. We are just lucky enough that some people find a few of those lucky animals.
Also in the snake world people do complain about hidden hets. if your working on a project and your expecting to hopefully get a certain percentage of one thing. You throw a new het. into the mix and its mess up everything. For example if your working on a project and it has taken years to raise the animals, breed them, feed them, house them and are working one a certain morph. Well your expecting to have say 12.5% chance of getting that special snake your working for. Well you discover that your snakes actually have a hidden het. in them and now your only have 6.5% of getting your snake. Thats how a hidden het. can ruin a project.
