- ... In the Lepidoptera, sex-linked genes have been found to be of importance for species differences in, for example, host-plant preference, and have been implicated in ecological speciation. Variation within species is typically not sex-linked. However, in the comma butterfly Polygonia c-album (Nymphalidae) an X-linked gene has been found to play a major role in determining differences in host-plant ...
