MONOHYBRID SEGREGATION IN MALVA SPECIES

The Fi-generations were uniform and the reciprocal crosses re- 

 sembled each other jx'rfectly. The characters of M. oxyloba 

 (fig. 1: 3, showed dominance in a rallier high degree but, by no

means, a complete one. The lobules of the leaves were not so sharp 

 pointed as in M. oxyloba, and the lobes of the sepals were more obtuse. 

 When growing side by side in parcels the hybrid and the oxyloba- 

 parent were rather easily distinguished from one another. 



Fo showed a discontinous variation as to the leaf shape and the 

 sepals, and these characters showed absolute correlation (fig. 2 and 3i.
