Many studies have been performed using twin subjects; however, the results are inconsistent, partly because of sample size, background assumptions, data limits or inaccuracies, incorrect zygosity classification, and/or lack of birth histories. “The genetics of handedness, cerebral dominance and lateralization,” in Handbook of Neuropsychology, Vol.
In summary, within the long history and large number of twin studies performed on handedness, a surprisingly large number of controversial findings have been reported, suggesting the complicated nature of this phenotype.
A powerful genie, if not brought into submission to the Will of God, is certainly capable of causing tremendous destruction of the lofty Islamic morals which Islam builds for its believers.
Muslim parents and teenagers are getting mixed messages about their roles.
They are uncomfortable in discussing it with their teenagers just as their own parents never discussed it with them.
They leave it up to the Sunday school to teach Islam and up to the television and the secular school system to teach sex education.
Victims were 71% adult females, 12% adult males, and 16% children.
There has been a long-standing debate on the complex correlation between the development of human hand preference and brain lateralization.

El-Kadi is vice chairman and clinical professor of neurological surgery at the University of Pittsburgh School of Medicine and serves as chief of neurosurgery at UPMC Passavant.
He specializes in the treatment of complex spine disorders, including spinal fusion and instrumentation, and minimally invasive spinal surgery, with a special interest in the removal of primary and secondary spinal tumors. El-Kadi received training in complex spinal surgery at Allegheny General Hospital in Pittsburgh. El-Kadi began his surgical career doing brain surgery, and the minimally invasive techniques used then have served him well as a spine surgeon.
El-Kadi graduated from the UNIV OF ALEXANDRIA, FAC OF MED, ALEXANDRIA, EGYPT (330 03 PR 1/71) in 1981.
He works in Freehold, NJ and 2 other locations and specializes in Rheumatology. El-Kadi is affiliated with Centra State Medical Center. In this mini review, the wide variety of twin studies on human handedness performed to date are introduced. doi: 10.1111/j.1469-7580.2008.00855.x Pubmed Abstract | Pubmed Full Text | Cross Ref Full Text Mc Manus, I.
