If you don't know whether the snake is homozygous or heterozygous, you just call it salmon. That's the name on its birth certificate -- Rich Ihle's paper in the Journal of Heredity.

If you can't tell the difference between a homozygous salmon and a heterozygous salmon except by breeding test, how is the heterozygous salmon a "visible het"? A "visible het" should be visibly different from both normal and the homozygous mutant form.
