  We add here compared to our former arXiv version an explicit expression for
the descendant ratio along the generations The equation that is added here
appeared in the Hebrew version published in BDD, Bar Ilan University Press, 23,
71, 2010, titled The distribution route from ancestors to descendants in
Equation 11. Otherwise, we don not change nor show here the paper but leave and
direct the reader to the former arXiv version with the above addition or to the
published paper in Hebrew.
