Generally a BCI has markings that look like this: ()()()()()()()()
A BCC has markings like this:}{}{}{}{}{}{}{}
I have seen variations of the BCI with widow peaks, but usually they have only a few... my BCI has 2 saddles with widow peaks, but no more, yet, he is a BCI... Maybe KLG will help explain the difference.
Recently I was reading that there is this HUGE debate over if a boa is a true BCI or BCC. Some say it is locality specific only and that nowadays you just dont know the locality so it is hard to tell, some count saddles, and scales, and so on so forth... but so far, every BCI I have seen, had the oval patterns with a few variations of widow peaks every now and again.
