The study I mentioned earlier is the Minnesota Study of Twins
Reared Apart Project.  A contact is:
Auke Tellegen, Dept of Psychology

Minneapolis, Minn  55455

See "Personality Similarity in Twins Reared Apart and Together",
J. Personality and Social Psychology, 1988, v54(6) 1031-1039.

This reports on application of the MPQ to 217 monozygotic and
114 dizygotic twins reared together and 44 monozygotic & 27
dizygotic twins reared apart.

Heritabilities of personality traits are estimated at .39 to .58.
The contribution of common family environment appears negligible.

Look it up for more...
