BP Gene Tutorial...?

[Will]

Is there anywhere on the 'Net that can explain to me the different morphs and genetics of BPs out there...? I've always liked and considered getting some, but when it comes to all the different morphs out there, I couldn't tell an ***hole from an earhole. I always see BP pics and think "Wow, that looks neat!" and that's as far as my thought process goes(which ain't too bad for me ). Obviously I can tell what a Pied, Axanthic or Albino is, basic stuff like that where the morph's name pretty much explains the genes involved, but give me a Clown and a Pastel Orange Ghost and I'm lost.

What really got me curious was these 2 pics from Corey Woods' post here (GREAT collection by the way!):
First Pic
It was part of a longer post and was titled "Pastel Orange Ghost with Pastel Females". Now to the uninformed mind(Mine), they all look pretty much the same. The guy in the middle looks like he has a lighter head, but I'll deal with my Ghost guess later. Comparing them to what I know normals to look like, 'Pastels' seem to be "more" Yellow, which suggests some form of Hyper-Xanthic morph.
This second one was titled "Pastel Orange Ghost with 2001 female Pastel as well as a 2003 Pastel Females" :
Second Pic
Now obviously the big female is a Pastel(the title gave it away), and 2 of the 3 youngsters are Pastels, but I might not be able to pick out the Pastel Orange Ghost if my life depended on it. The black parts of the baby in the the middle seems to be a lot lighter than the other 2, but what makes it a Pastel Orange Ghost(if that's even the right one, if not I'm in more trouble than I thought, lol)...? Is it a combo of Hyper-Xanthic(which I guessed to be the Pastel morph) PLUS some form of Hypo-Melanism...? I could be way off with those guesses, what the heck do I know, heheh...? Could someone maybe while they're at it, explain those 2 morphs, was I at least in the ballpark with the guesses....?

Anyways, is there something out there that can explain these different morphs and what is at play to create them...? Some morphs seem to be small variations and are tough to spot unless you know what to look for. As well as how these morphs breed out(dominant/recessive, co-dominant that kinda deal.). It would be much appreciated...
