Abstract
This work deals with stochastic modeling in biological populations. We develop a two-sex branching process as an appropriate mathematical model to describe the demographic dynamics of biological populations with sexual reproduction. We assume several mating and reproduction strategies. Moreover, unlike other classes of two-sex branching processes where mating and reproduction are influenced by the number of couples in the population, we now consider the most realistic case where both (mating and reproduction) are affected by the numbers of females and males in the population. We study the extinction/survival of populations modeled by such two-sex branching process.
