Can you guess?

I'm compiling some clues for everyone.

-no supers or recessive
-3 genes
-all 3 genes been around forever
-double has been produced before
-it has spider in it
-he bred a double to a single
-double is listed in his collection, nothing about the single though.

Here is a list of all his doubles from the collection.

black pastel sable
black bee
black butter
black pastel red stripe
black pastel trick
black pastel yellow belly
black pewter
blond blast
blond bumble bee
butterbee
butter nazca
butter sable
enchi sable
firefly
leopard spider
mojave nazca
mojave red stripe
mojave sable
mojave spider
Nazca woma
butter pastel
pastel spector
pastel woma
pastel yellowbelly
redstripe pinstripe
yellow belly nazca
yellow belly spotnose

If we reduce the newer morphs. Nazca, red stripe, leopard, sable, spector, trick

We are left with these animals:

black bee
black butter
black pastel yellow belly
black pewter
blond bumble bee
butterbee
firefly
mojave spider
butter pastel
pastel woma
pastel yellowbelly

One of those above must be the sire or the dam, unless he lied to us.

I feel like the double is either a spider mojave or a black bee. I also believe that one of the genes has to be a black pastel, no other animal would produce that grayed color.
