Genetic effects of irradiation on early mortality in swine.

Abstract

Mammalian studies in radiation genetics have been confined principally to mice. The major emphasis has been on the nature and rate of changes at specific sites in the chromosomes (RUSSELL and RUSSELL 1959). Genetic effects of neutron radiation on the longevity of the first generation offspring have been reported. The work with swine was undertaken to extend the mammalian studies to another species. This report deals with the average effect of paternal irradiation on survival at birth and during the first three weeks of postnatal life. Corresponding effects on weight are given elsewhere.
