Balanced sex ratio evolves by a process known as frequency-dependent selection of the minority sex. Efforts to test this theory have focused mainly on experimental populations. Heterogametic sex has greater influence over the sex of the offspring. We tested the prediction that a smaller human population should favor male offspring. Our findings reveal that size of the population has significant inverse correlation with male proportion. We also present evidence for frequency-dependent selection of the minority sex and evolution of balanced sex ratio in isolated human population.
