Jukes The \Jukes, The\
   A pseudonym used to designate the descendants of two sisters,
   the ``Jukes'' sisters, whose husbands were sons of a
   backwoodsman of Dutch descent. They lived in the State of New
   York, and their history was investigated by R. L. Dugdale as
   an example of the inheritance of criminal and immoral
   tendencies, disease, and pauperism. Sixty per cent of those
   traced showed, degeneracy, and they are estimated to have
   cost society $1,308,000 in 75 years.
