While my children are mixed, and three of them rock 3 types curls, the other is a 2 type with waves, there are several 3 type curlies on their Italian and Hispanic sides who are not mixed. In fact, my son's hair is exactly like his Italian cousin and both her parents are Italian. Also, My father has soft 3b hair, tho his gran is racially mixed, he's a dark skinned man who has always considered himself just Black.
