Great job! I hope it is okay to expound a bit further on your article.
The common accepted theory is that the black is dominant over the red in CRS. This is if we are dealing with homozygous backgrounds.
Homozygous means having identical pairs of genes for enough breedings. You know that there is almost no chance of that particular shrimp throwing anything else but a phenotype (lookalike) of itself.
Creating a homozygous recessive (CRS) in theory is pretty easy- since the recessive is lowest on the totem pole, no other color should pop up. HOWEVER, there are always surprises in backgrounds. That is why breeders often do test breedings. (Ie. Testing a "Pure" red strain by crossing with a golden to see if any goldens are thrown. If so, it has golden in the background close enough that it is not really Pure.)...or breed lines for several generations to make sure there are no "surprises" in the background.
So assuming the crossings are from "Pure" homozygous shrimp:
CBS x CRS = CBS
The CRS is now hidden in the background of the CBS offspring. This is called heterozygous. Or het for short. The pheonotype, however, is CBS.
As mentioned above in the article: CBS (het CRS) x CBS (het CRS) = CBS + % CRS

TB, unfortunately, we really don't know too much about. If there were just two colors, perhaps it would be more black and white. (Pun intended.) But there's a lot more than that. Often the punnet squares just don't work on TB. Why?
Well, there's also the real life challenge of hierarchy of genes and recessive genes. For example, let's say green was an actual color for crystals. The hierarchy may look like Green > Black > Red
Black x Red = Black
Black x Green = Green
Red x Red = Red
Green x Red = Green
Now all these genes are involved and can throw Black, Red, or Green. Trying to separate these out can be quite confusing with all the shrimp having different combinations of backgrounds and throwing different types... and this is just an example of 3 types of genes involved!...and just simple dominances and recessives!
I'm sure part two by 00camadro16 will discuss co-dominance and modifiers, which can be more confusing yet and applies often to TiBs and Neos as well as TBs!
Bravo on a job well done!
