Abstract

Variation in sex ratios is a poorly understood phenomenon that despite having been extensively studied since Darwin, still holds many intriguing questions. In many species sex ratios are unequal, not holding to Fisher’s principle of equal sex ratios. Explanations vary a lot, and no single theory is sufficient to explain all that is found. Inherently linked to sex ratios is the system that determines the sex. These systems also show much variation, and their evolution is poorly understood. Currently, many interesting developments involving both sex ratio and the sex determination are underway, most notably in arthropod species. Extreme sex ratio deviations occur, and the concurrent evolution of the sex determination system might provide insight into the dynamics and origins of sex determination systems.
