Developmental genetics

A whorl whose spin may track handedness

In developmental biology and human genetics the structure is the parietal scalp hair-whorl, or trichoglyph: the point from which scalp hair radiates in a spiral, whose clockwise or counterclockwise direction is laid down during fetal development. Klar's 2003 Human handedness and scalp hair-whorl direction develop from a common genetic mechanism and Schmidt, Depner, and Kabesch's 2008 study examine whether whorl direction correlates with handedness and might share a genetic basis. This is exactly the hairdresser's cowlick, studied as a morphogenetic and laterality marker rather than a styling obstacle: the same construct under a different name.[1][2]

Unit
The handedness (rotational direction) of the parietal hair-whorl
Recovery means
Not applicable
Measured by
Scored as clockwise versus counterclockwise whorl direction and tested against handedness and other laterality traits
