We're working on both strains of albino!...I produced the first "Harlequin" boas in 97 from 2 normal looking siblings,(they had great color,but,niether were aberrant.)they were obtained from a girl in Fla. in 93...They have proven to be some form of dominant mutation that affects both pattern,and,coloration.(I say "some form" because,in 3 litters this year,I have not seen the 50/50 split that would be expected from "co-dominant" expression? if this happened in one litter,I'd tend to think I just "beat the odds"...but,THREE litters?,4 if you count the little het. that would be some serious Irish luck!?)I can say with absolute certainty,it sure isn't recessive though!(*lol*) several people have mentioned the similarity in pattern anomolies,with those seen in "Jungles",however,since we were unable to trace their exact origin,it's important not to jump to conclusions,or,become too presumptuous in regards to those similarities,there are some unique differences too,and,it's become an extremely rewarding project,with seemingly endless variation.
