MASS STUDIES IN BUILD. 



Table 13. — Matings of fleshv X fleshy parents. There are 33 matings of 

 this type. They yielded 159 offspring: 15 S, 62 M, 61 F, 21 VF. 

 The progeny show a rather high variability (fig. 19). 



Table XIV. — Matings of fleshv X verv fleshy parents. There are 30 matings 

 of this type. They yielded 146 offspring: 1 VS, 7 S, 52 M, 51 F, 35 

 VF. The progeny are very variable (fig. 20). 



Table XV. — Matings of very fleshy X very fleshy parents. There are 7 

 matings of this type. They yielded 37 offspring: 1 S, 12 M, 11 F, 

 13 VF. The progeny are exceedingly variable (fig. 21).

The diversity of the distributions of the progeny of the various 

 matings and the great difference in their variabilities indicates that 

 there is not only an inheritance of tendencies to particular types of 

 build, but also that there is a strong evidence of some sort of Men- 

 delian inheritance.
