What is the genetics for left-handedness?

Population studies on twins and non-twins suggest a genetic component to handedness...There is far from any conclusive evidence. As in most behaviors, it probably involves a group of genes.

Here are two good studies:


Klar, A.J.S., A Single Locus, RGHT, Specifies Preference for Hand
Utilization in Humans, Cold Spring Harbor Symposium on Quantitative Biology,
CSHL Press, (1996)

Orlebeke, J.F., Left-Handedness in Twins: Genes or Environment?, Cortex
32:479-490 (1996)
