Background: In a previous paper, we showed that greater sibling diversity among sexual offspring might help to maintain sexual reproduction in environments that are spatially heterogeneous and temporally fluctuating and in which sib-competition is very intense.
Question: Can sexual reproduction be maintained in the face of the two-fold cost of sex under milder selection pressure, environmental variance, and reduced genetic diversity?
Methodology: Mathematical and numerical analyses of the sib-competition model with several modifications.
Conclusions: The advantages of sexual reproduction are attenuated by milder selection pressure and environmental variance but enhanced by reduced genetic diversity. Sib-competition plays an important role in maintaining sex when the appropriate conditions are present.
Keywords: evolution of sex, sib-competition, milder selection, environmental variance, reduced genetic diversity.
