Myths of Human Genetics.
Seminars in Cell and Developmental Biology 20: Conveniently, the gay men were highly concentrated in one area of the beach. Journal of Genetics 170: And 23 of them were born in 5 Chen , 2 Shu , 9 Chou , and 7 Wei time period 51. This assessment was reinforced by the dearth of females and children on the beach... The whorl can be particularly hard to see in people with long or curly hair. Scott, N. Human handedness and scalp hair whorl direction: Klar, A.
According to Chinese legend if a person was born during the hours of Chen, Shu, Chou, or Wei periods, he or she should have two or more hair whorls. A person with an rr genotype has a 50 percent chance of being left-handed and a 50 percent chance of having a counterclockwise whorl; therefore half of all left-handed people would have a counterclockwise whorl, and half of all people with a counterclockwise whorl would be left-handed.
Frontal 'cowlicks' are usual in the FG syndrome Thompson et al. In this model, a person with an RR or Rr genotype is right-handed and has a clockwise whorl.

References Annett, M. Left, right, hand and brain: In the research on human developmental biology, there are articles which suggest that handedness and the direction of scalp hair whorl rotation develop from a common genetic mechanism.
Please join your colleagues by making a donation now and again in the future. Klar 2003 provided evidence for a link between handedness 139900 and the orientation of hair whorls on the scalp, suggesting the possibility that the same system that patterns hair may also play a role in left-right asymmetry in the brain.
