Extremely abnormal segregates, 

 judging from the records, have a 

 leaf count as low as 24 and a height 

 of only 12 "2 dem. A survey of 

 the data in Tables 22 and G shows 

 there is some correlation between 

 height and number of leaves. In 

 addition to the characters just 

 mentioned, these segregates differed 

 as to color, habit of growth (bran- 

 ching or non-branching), leaf charac- 

 ters, flower characters and many 

 others not so easily noted. 



b) Fasciation X calycanthemy 

 and reciprocal. 



This cross was especially in- 

 teresting for two reasons; first, 

 the segregation of two characters 

 which were more or less associa- 

 ted in the same organs, and second 

 on account of the numerous modi- 

 fications of fasciation, even in AA 

 segregates. 



In the first case, both charac- 

 ters had given simple 1:2:1 ratios 

 in an F2 generation obtained by 

 crossing each of them separately with the normal 402. (See Table H.) 

 Both were partial dominants when heterozygous, hence in monohybrid
