This generation produced fine large seeds of nearly the Telephone 
type throughout. Green and yellow seeds were always quite 
distinct, but smooth and wrinkled were rather more difficult to 
distinguish, and there was a slight doubt in one or two cases. 
In the above cases as in others, a Mendelian total was arrived at 
when a sufficient number of plants were taken, in spite of the very 
small samples which individual plants afforded.
