Hi Julie,
The reason why its not appropriate to call your geckoes tangerine hets is
because the
tangerine trait is not dependent on a single gene.
If there was a single gene for tangerines, it would be expected to be
recessive,
and all offspring from crossing two tangerine parents would be similar
tangerines and not the mix you usually get.
The term het (hetrozygote) is usually applied to single-gene traits like
albinos and leucistics.
If you cross 2 albino hets or 2 leucistic hets, the albino or leucistic
trait will reappear in 1/4 of the offspring.
The reappearance of the tangerine trait after crossing tangerine "hets"
would not be as reliable
and that is why it could be bad business to sell "tangerine hets".
