Agent-Based Modelling shows that Operation of Fisher’s Principle does not explain Zero Heritability in Human Offspring Sex Ratio

2023-04-06

Abstract excerpt

The evolutionary basis of the ratio of male to female births has been a focus of research for over a century. Fisher’s principle suggests that offspring sex ratios remain roughly equal due to negative frequency-dependent balancing selection: individuals with alleles that produce the rarer sex have greater fitness, increasing these alleles’ frequency until the sex ratio is balanced. However, recent analysis of Swed...
