At the outset, I respectdfully request that my questions not be published:
My boyfriend has a double hair whorl. I've read that double hair whorls are pretty rare and can indicate abnormal brain growth. My boyfriend has a tendency to be a bit hyperactive
and he has suffered with substance abuse issues in the past, but he made straight A's in school and has a graduate degree, so other than those things just listed, he's very intelligent and seems pretty normal otherwise.
We are planning to get married and have children, so I'm worried that this double hair whorl could be genetic, so I have the following questions:
1) Are double hair whorls indicative of abnormal brain growth in the majority of cases?
2) Are double hair whorls genetic?
3) If a parent has a double hair whorl (but has not been diagnosed with a mental disability), does the presence of the double hair whorl in the parent increase the risk that a child will be born with a mental disability?
