ToblcIX. — Matings of slender X very fleshy parents. Thert are 16matii 

 of this type. They yielded 50 progeny: 7 S. is M. 17 F, 8 VF. I i 

 progeny are very variable (fig. 15). 



Tabic X. — Matings of medium X medium parents. There are 93 matinge 

 of this type. They yielded 332 offspring: 2 VS. 40 8, 201 M B2 1

 all individuals of medium build are not "heterosygotes" ; but that 

 there is also a "medium" race.
