Can anyone comment about how right- and left-handedness is 
inherited?  My son (2 1/2 years old) seems to prefer his left
hand for accomplishing certain tasks such as eating, though for
other things he prefers his right.  My wife and I are both right-
handed.  There are no lefties in my wife's family that we know 
of, but my father's brother is left-handed (don't know about my
paternal grandparents). Is handedness a Mendelian characteristic
or are other factors involved?  Thanks!!
