Table X(B). — Percentages of offspring in states i, 2, and j to correspond to states i-i, 

 1-2, 2-1, . . . of the sires and paternal granddams 



"See footnote, Table 1(B). 

 Table XI(A). — Correlation between offspring and paternal granddams 



r= — o.oioo±o.oo84. 



Table XI(B). — Percentages of offspring in states i, 2, and j to correspond to states 

 J, 2, and J of paternal granddams 



Tables XII (A) and XII(B) represent the distribution of paternal 

 grandsires and sires of the offspring treated in Tables II and IX. Here 

 again we note that there is no significant difference whether paternal 

 grandsires are singles or twins. This conclusion is further supported by- 

 obtaining from Table XIII (A) the correlation coefficient 



r= —0.0147 ±0.0097. 



We are thus unable to assert the existence of a significant correlation.
