WebFisher's principle explains why for most species, the sex ratio is approximately 1:1. Bill Hamilton expounded Fisher's argument in his 1967 paper on "Extraordinary sex ratios" as follows, given the assumption of equal parental expenditure on offspring of both sexes. Suppose male births are less common than female. WebPrinciple: Karl Fischer titration is used for many substances as a reference method, and is a chemical analysis based on the oxidation of sulfur dioxide by iodine in a methanolic hydroxide solution.
