Abstract

Small populations at risk of extinction due to threshold or competitive exclusion have a vested interest in rapid growth. Taking chance of survival into account for diploid populations, Fisher’s theorem predicts a sex ratio favoring females under certain circumstances. Theoretical consideration of competitive exclusion shows such circumstances are reasonable under accepted modeling assumptions.
