Thus, starting with a plant of about 70 colour-intensity we arrive by selection 
of self-fertilised plants at mean family intensities of 100 in one direction and 32 in 
the reverse direction. 
In another series, starting with a homozygous dominant plant of colour- 
intensity of about 11, I have by selection obtained plants in which the corolla 
exhibited no general tint. On selfing the pale plant no white plants occurred,
