Briefly, the result of crossing ii long-glmned wheat with a short- 



gluiiied is this :- 



Along with the ordinary segregation there is established in the F.;. 

 generation a kind of telescopic effect, whereby the means of the two 

 hoiiiozygote curves are brought nearer to that of the heterozygotes 

 than the means of the parents would actually be. This condensation 

 persists right through into the F,. generation in which, owing to the 



possibility of isolating the
