Abstract
The differences of birth-weight distributions before and after selection by the different components of perinatal mortality were studied for all single babies born in Italy in 1974. It was found that: (i) In mature babies the selection is mainly stabilizing while the directional type is almost negligible. (ii) In immature babies both stabilizing and directional selection are at work, greatly modifying the birth weight distributions.Keywords
