Abstract
Biparental demographic models violate linearity. In their early dilute stages before limited environment resources bring need for competitive selection, 1st-degree-homogeneous relations may be used. For them, a reproductive-value function of the initial coordinates is defined to recapitulate their contribution to the asymptotically dominating mode of exponential growth: now the generalized Fisher reproductive value of one sex is altered by relative numbers of the other sex. The new reproductive-value function is also derived for general systems of homogeneous 1st-degree differential and difference equations, and is shown to grown from the start at the asymptotic growth rate.This publication has 5 references indexed in Scilit:
