Fig. 2 The class distributions according to factorial units affecting facet 

 numbers in populations of ultra-bar females (C/), bar females of the second low 

 selected white-eyed generation from which ultra-bar was derived {B), and full- 

 eye {F). The class frequencies are in per cents of the whole population and are 

 therefore directly comparable. The zero of the factorial scale is the mean value 

 of the unselected white bar. The same material is represented in tables 1 and 3.
