Directional selection on directional asymmetry: testes size and secondary sexual characters in birds

Proceedings of the Royal Society of London. Series B: Biological Sciences, 1994
A standard example of directional asymmetry with one side of the body having a larger character value than the other is testes size in many vertebrates. The relation between directional asymmetry in testes size and the expression of secondary sexual characters (a measure of phenotypic quality) in two bird species, the barn swallow, Hirundo rustica, and
