Dependence of the Sex Ratio at Birth on the Age of the Father

Abstract

RECENTLY I have attempted to develop a general theory of ageing applicable to mammals1. This theory assumes that, during the life-time of the animal, whole chromosomes, which are contained in the somatic cells, suffer a total loss of function in a single random event. It further assumes that the probability of such an event remains constant throughout life-time and that it is the same for all individuals of a given species.
