You know it, Tim!
The T+ means that they are Tyrosinase Positive Albinos, which essentially means Tyrosinase is present in the synthesis of melanin or black pigment to you and I! There are 2 proven strains of Albinism in Blood Pythons, these being the T+ and also the T-, I'm sure VPI are working to prove/disprove this with Lavender/Orange animals too, but I suspect they are just a different line of T- Albinos. Cherry Bombs refer to a line of T+ Albinos descending from one WC animal who was particularly red! It's late here.....I hope that made sense.
I'll get some fresh shots of the parents done some time this week if I get the chance!
