Mathematical Modeling of Sexual Ratio of Biological Populations

Abstract

Using a modified simple model proposed by Redfield we try to explain population dynamics of species with changing sexual ratio. In the model the probability of offspring's sex is represented by a number in parents' genes and so that can be an adopted parameter to the current environment. According to our results the population can survive under harsh condition only if the number of males and the number of females are equal, only in this case the population posses more genetic viability.
