Using the StarTrack binary population synthesis code we investigate the
properties of population of compact object binaries. Taking into account the
selection effects we calculate the expected properties of the observed
binaries.We analyze possible constraints on the stellar evolution models and
find that an observed sample of about one hundred mergers will yield strong
constraints on the binary evolution scenarios.Comment: Invited talk at "The Astrophysics of Gravitational Wave Sources"
