Implications of the Trivers-Willard Sex Ratio Hypothesis for Avian Species and Poultry Production, And a Summary of the Historic Context of this Research

Abstract

At a theoretical level, the Trivers-Willard Sex Ratio Hypothesis applies to both avian species and mammals. This article, however, conjectures that at the statistical level, sex ratio effects are likely to produce sharper numerical variations among birds than among mammals. We explain this greater statistical variation should likely have beneficial implications for increasing the efficiency of world-wide poultry egg (and perhaps also meat) production.

A 30-minute invited talk summarizing the contents of this article was presented on June 18, 2017 at the Binghamton NEEPS-2017 Conference. The Version-1 June 27 (2017) draft of this paper was similar to the 30-minute talk I gave at Binghamton University, and it was disseminated nine days after this talk. This second draft is more detailed and polished because it contains Section 4's added evidence
