A novel test of the phenotype-linked fertility hypothesis reveals independent components of fertility.

Proceedings. Biological sciences - 7 Jan 2004

Pizzari Tommaso, Jensen Per, Cornwallis Charles K

Abstract excerpt

The phenotype-linked fertility hypothesis predicts that male sexual ornaments signal fertilizing efficiency and that the coevolution of male ornaments and female preference for such ornaments is driven by female pursuit of fertility benefits. In addition, directional testicular asymmetry frequently observed in birds has been suggested to reflect fertilizing efficiency and to covary with ornament expression....
