Summary
The variations of the dorsocentral and scutellar bristle patterns founded in two bidirectionaly selected lines are discussed in terms of the Richelle and Ghysen model. The phenotype obtained through selection for bristle suppression can be accounted for by a decrease in chaetogen production. Extra bristles can be accounted for by an alteration of the response of the cells to positional information.
