I know there are already threads on this ... I've read them, but I feel like the information is in bits and pieces and I'm trying to get a sense of the whole story.

My questions are:

1. Are citrus, fader, whiteout all the same thing?

2. Are they alleles on the pastel locus, or is it a gene that can be separated from pastel? (A "hidden gene," if you will )

3. Is the wacky stuff produced with citrus consistently produced, or is it random? In other words, if I bred citrus x lesser, would all of the citrus lessers be wild looking or would some be bland?
3b., if some are bland-looking, do those carry the citrus trait unexpressed, and can they produce wacky citrus stuff? Or are they a dead end?

4. Is there any way to distinguish a "citrus pastel" from a regular pastel?

and finally, 5. Is this one of those genes that lightens up as it ages?

I have seen a number of these up for sale, and pricing seems to be all over the place. I'm interested in breaking into them, as I love the crazy stuff you can make, but I'm hesitant without knowing the whole story -- especially since I'm having a hard time distinguishing a heterozygous citrus from a regular ol' pastel.

Thanks all!
