Parasitism of asymmetrical pelvic phenotypes in stickleback

  • Published 2007
Subtle departures from biliteral symmetry in morphological traits result from environmental and genetic stresses and may signal an inferior genetic background. Because one correlate of an inferior genome is reduced resistance to infection, such asymmetry may provide a phenotypic signal of susceptibility to parasitism. I tested this hypothesis in a population of threespine stickleback (Gusr~ro.srcu.s c~c~ulec~rus) with cestode and nematode infections and bilateral asymmetry of the pelvis… CONTINUE READING
