Almost all BGJD's you cant tell the difference from regular JD's. However, Ormed, one of the original breeders and distributors of EBJD, was able to creat some BG's that were clearly JD but had strong EBJD physical traits. They were posted on aquabid a few years ago. They looked just like jd's but had EBJD like traits and colors that was just phenomenal.
Most BG's tend to look better because the breeder took better care of them versus a regular JD. All of my BG's had bigger pearls, better colors, and grew faster than my regular JD's.
This is a valid point and may very well be true. However, this would be the only way to tell the difference between a normal JD and a BGJD from a physical standpoint. This guy Ormed, the BGJDs he had just had great genes and tremendous color, but you can't say they were displaying EBJD-specific traits, because that would be impossible. BGJDs are nothing more than a carrier of a RECESSIVE trait, meaning you can NEVER decipher one from a regular JD without breeding it or knowing its bloodline.
