shifts a chance distribution of handedness toward the right. Variability for
this gene could throw light on why people differ in their talents, abilities and

possible relevance for educational progress, dyslexia, spatial reasoning,
sporting skills and mental illness,” explains Dr Annett.

schizophrenia and autism.
