It's in German but google translate translates it fairly well (you always get a few funny words that don't make sense with Google but it's readable at least)
Basically the gist is that are BB's really Taiwan Bee's or are they Blue Snow Whites?
In the beginning of Taiwan Bee's, there was no blue bolt's, only King Kong/Wine Red variations. As the TB's were far and few in between and very fragile, they bred them with other Bee shrimp and cross the F1's with each other and other TB's (mischlings, we know lots about this and that it was done) and this produces more TB's.
During this crossing times, they used snow whites as well and out of that came the odd blue bolt.
They do make a few valid points.
When you cross any variations of WR and KK's, you get both. Even KK x KK you will get WR's and you seem to get various grades out of them from 2 bar to extremes and you get a mix of red and blacks, more so than breeding CRS x CBS.
When you cross BB x BB, you get BB'. You don't get any KK's or WR's out of the bunch, only BB's of various blue from the headgear to full body blue.
If this is the case, it's pretty obvious that shadow panda's and shadow KK's came from a BB x TB crossing a few times to get the blue to express.
If you're kept nice snow whites for a while, you may be seen bits of blue in them , especially the cheek area and this is without any TB gene influence, so the blue is already there in some snow whites to a very small extent, so did a TB crossing give them the ability to express that further? The thing about TB's is the color is intense, it seems to always be solid unlike CRS/CBS, so a bit of TB genes' in a snow white might help them express that blue to be a BB.
So the question is, are blue bolts really Taiwan Bee's or are they just a blue snow white that the TB's were used at one point to express the blue better but now would be their own sub-branch or sub-color of the common bee shrimp?
