MENDELIAN INHERITANCE IN OENOTHERA PRATINCOLA

TABLE 9 

 Analysis of the FI generation of the cross mut. formosa X /. typica E (a'0ff X afiff). 



All of the plants are revolute-leaved. Of the 235 plants grown to maturity, taken in part 

 from each of the nine cultures, 230 were mut. formosa, and the remaining 5 were plants of other 

 revolute-leaved types 3 of mut. revoluta, 12 1 of mut. setacea, and 1 of mut. albicans (?), 13 all 

 of these being types thrown by pure strains of mut. formosa. 



TABLE 10 



Analysis of the FZ generation resulting from self-pollination of f. typica plants chosen at random 

 from the FI generation (see table 9} of the cross mut. formosa X f. typica E (a'ftjf X a&ff). 



All of the plants are revolute-leaved, as in the FI generation of this cross; that is, the inher- 

 itance is matroclinic. Of the 72 plants grown to maturity, taken in part from each of the four 

 cultures, all proved to be mut. formosa.
