Just from my experience looking at people's fotki's on this site generally a lot of different curl types exist in every race. I think sometimes people think one curl type can be the only one in a race, but that's really not true. Generally one is prevalent, but there are lots of different hair types as well? For myself, I am several different types of caucasian--Irish, Scottish, and British I believe--and I have looser curls that still have 3b tendencies.
