Simultaneous analysis of handedness data from 35 samples of twins (with a combined sample size of 21,127 twin pairs) found a small but significant additive genetic effect accounting for 25.47% of the variance (95% confidence interval [CI] 15.69-29.51%). No common environmental influences were detected (C = 0.00; 95% CI 0.00-7.67%), with the majority of the variance, 74.53%, explained by factors unique to the individual (95% CI 70.49-78.67%). No significant heterogeneity was observed within… CONTINUE READING
