Heterozygous corn snakes?

So I understand the whole genetics component of it, but I was wondering:

What do these snakes actually look like?

I'm not interested in breeding so the genotype isn't really important. But if I order one online, will I just be guaranteed it could be any color except the one it's listed with?

(specifically referring to this site: http://www.cornsnake.net/pricelist.php?catid=2)

Thanks so much!

Are you looking for a particular color morph, like lavender or butter or bloodred, or do you want a normal (wild-type) color?

If you want a lavender, it will be sold as a lavender. That means it is homozygous for lavender- it got one lavender gene from each parent.

If you want a normal, that means it didn't get a pair of color genes from both parents, but it may have got one gene for lavender, meaning it looks normal, but carries that one lavender gene- it is het(erozygous) for lavender. In the future, if bred, it can pass on either it's one normal gene or it's one lavender gene to future offspring.

So on Don's site, you click on lavender. It says the homozygous lavender, which IS lavender in color, is $100. A normal colored corn, het for lavender, is $50.

Now you can also buy (maybe not from Don, but somewhere) a homozygous lavender snake which may be het for other things- bloodred, amel, etc. That means it carries one copy of that gene, but it is not expressed in the snake's phenotype- what it looks like- because you need two of that gene, one from each parent, to be able to see it.
