In the last generation it will be seen that there was no sharp separation of the 
plants into two groups attributable to the two grandparental factors. Thus, in 
the case of {A x G) pi. 2 (50°) the offspring are not clearly divisible into those of 
100" resembling A, and those of 35" attributable to G ; in other words there was 
no obvious segregation into two degrees of pelorism. 
On the factorial and chromosome hypotheses we must suppose that the factor 
or factors governing the peloric character tend to become mutually changed and 
intermediate in nature when the male and female chromosomes containing the 
factors for the two degrees of pelorism lie alongside each other in the zygote. 
It will be of interest to obtain a general measure of the strength of inheritance 
between mid-parent and offspring with respect to the transmission of the degree 
or intensity of pelorism. For this purpose only recessives were used, involving
