MENDELIAN INHERITANCE IN OENOTHERA PRATINCOLA 



29 



TABLE 5 

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



The cultures consist of flat-leaved types only, but as seedlings the plants show the effect of 

 crossing in irregularities in their leaves, the blades being unsymmetrically developed. Of the 

 95 plants grown to maturity, taken in part from each of the six cultures, all proved to be f . typica 

 except 1 plant, which was an undescribed flat-leaved mutation, mut. dimorpha. 



TABLE 6 



Analysis of the F 2 generation resulting from self-pollination of f. typica plants chosen at random 

 from the FI generation (see table 5) of the cross mut. formosa X/. typica C (a'ftjfX a&FF). 

 Each of the cultures contains both flat-leaved and revolute-leaved plants in approximately a 3:1 

 ratio. 



11 The asterisk (*) in this and subsequent tables indicates that seeds from a single capsule 

 were sown.
