BP = Enchi/100% Het Albino/100% Het Gravel or Yellowbelly
Enchi is a bit obfuscated in this one, but there is enough there to ID it.
Stones are assorted but I see that most of them are from New England and Brazil, with some scattered African specimens, and a few from various parts of the USA.
According to the statistics online: The odds of a *visible* chimera are roughly estimated as 1 in 100,000.
If I have been producing ~300 mice/week (low estimate) for the last 10 years, I have produced: ~156,000 mice...Which means I have been overdue to find one...
A Tetragametic Chimera is formed from 2 fused embryos or an absorbed twin. I think that is what is going on here.
Unfortunately this is a non-heritable event--but that is not going to stop me from trying to produce more.
