There's a few different blood lines of which aren't supposed to be compatable with each other like albino (kahl, sharp, vpi t+, ca t+)
Ron St pierre lines was from a very dark central American boa found in el Salvador then worked on by vin russo
John berry's line of blood I'm sure are from Nicaraguan boa blood line
This is why most blood boas are small being from dwarf central American blood line
Sunset I'm sure are line bred from hypo hog Island breeding the reddest to the reddest etc
Hope this helps
