From: Selection for Male Weapons Boosts Female Fecundity, Eliminating Sexual Conflict in the Bulb Mite
Morph-specific, bidirectional artificial selection on weapon size (relative width of the third pair of fighting legs, highlighted) of Rhizoglyphus echinopus fighters caused a divergence of about 6% (yellow arrows) after nine generations. Selection was only applied on fighters, but scramblers (the other male morph) and females (not shown) showed a correlated response of about 2–3%, even though they lack fighting modifications in their third pair of legs. Images are manipulated to show the magnitude of difference; original data from Buzatto et al.12.
