Abstract

We have studied the impact of natural selection on the Italian population, analysing the relationship between stillbirth and three related variables: birth weight, birth order and maternal age. A progressive relaxation of selection with time has been demonstrated by the reduction of the Haldane index calculated with respect to the three variables.
