I'm trying to figure out how I got what looks to be a cambodian coloring with a white butterfly pattern out of my pink/blue butterfly sibbling pair...90% of the fry are clones of the parents then I have 10% that are platinum bodied with red tails with the butterfly pattern....

Do you have any insight on this? These kids are 10 weeks so they should have colored up by now......

http://www.geocities.com/dynarb/genetics.html This link will tell about the cambo gene.
All I do know is that the cambo gene is recessive. Your BF pair must have cambo in it's background. The genetics of betta is so confusing.
I am baffled as to how my multi pair came from a Mustard gas pair?

The platinum could simply be a recessive trait, or the parental coloring could have been a dominant trait that "covered" the platinum. Either way would get pretty close to the percentages you're looking at.

In school, when they're talking about genetics, they talk about single traits, like whether or not rabbit ears stand up. They don't cover stuff like animal coloring, which occurs in layers. A betta could carry the genes for three different colors/combos, and only show a single color, or it could be a rainbow like my little Ranmaru. It's a bit beyond my comprehension at this point. That's why I'm starting simple with my guppies; purple Moscows, and when I start playing with genetics, I'm going to introduce either blue or black Moscows.

Likely it was a recessive trait of some kind. You never know what you're going to get out of a spawn! They're gorgeous regardless. The butterfly effect looks neat!

Thank you Allie for the link.....I agree Red, the butterfly pattern is very striking...Sir, I wonder if I bred one of the girls to my platinum boys what I would get...Any thoughts on that?

I'm guessing (and this is just a barely educated guess) that you'd end up with a higher percentage of platinums, with the rest being the butterfly.
Unless...
The platinum is a recessive trait and the butterfly you choose happens to not have that trait.
There are too many variables to know what's going to happen based on one set of fry (at least with the info I have. I'm sure someone out there knows enough to make the call better).

Out of curiosity, are all of the platinums little boys (or are the not old enough to tell yet)?

Everyone's pretty much answered it already... Cambodian (absence of black pigment on the body) is recessive to normal black (ordinary dark bodied fish). So those little guys, from what I can tell are cambodians with lower, wild-type iridocyte amounts (recessive to the spread iridocytes you see in any iridescent fish). Since both parents are butterfly, that part's not expected, but with the wild-type iridescence and the absence of black the only colour that's really showing is the red!
lol, the strange ones in a bunch are great for letting you know what the parents are hiding in their genetics... in this case, both are carrying cambodian and normal iridocytes.
Breeding to a platinum would probably get you around 1/2 with the dark bodied type, and 1/2 with the light bodied type. Unless the parents were carrying red loss or non-red, you'd probably end up with red fins and likely at least some with butterfly patterns. A lot of the cambo types would probably have the really white/shiny bodies of the platinums, depending on if the plat was carrying normal iridocytes or not.
These things get much easier to predict after a few generations of sib pairs and seeing what pops out, or at least knowing the ancestry of the fish... my mg cross pair threw a lot of cambodians, but since I knew their grandmother was herself a cambo, it wasn't unexpected.
