A sex ratio is the ratio of males to females in a population. As explained by Fisher's principle, for evolutionary reasons this is typically about 1:1 in species which reproduce sexually. [ 2][ 3] However, many species deviate from an even sex ratio, either periodically or permanently. Examples include parthenogenic species, periodically mating ...
