INHERITANCE OF VARIATES IN THE ARMADILLO 165 



The polyembryonic and parental correlations of the three bands 

 will be more readily compared from the following tabulation: 



Polyembryonic 'r' . 

 Parental 'r' 



BAND 1 



0.4657 ±0.0576 

 0.4542^0.0598 



BAND 9 



0.3625 ±0.0649 

 0.3114 ±0.067 



0.5796 ±0.0482 

 0.5964 ±0.0434 



In none of three bands dealt with is the difference between the 

 polyembryonic and the parental correlation as great as the prob- 

 able error and in one of the three bands (9) the parental correla- 

 tion is a little larger than the polyembryonic. It will be further 

 noted that the average uniparental correlation is 0.492, which 

 is very close to that determined for the banded region as a whole. 

 This must be true for the nine bands for it is these bands that make 

 up the banded region. 



6. SUMMARY FOR THE BANDED REGION 



1. Polembryonic correlation for 56 sets of male quadruplets is 

 0.9294 ± 0.0057; that of 59 sets of female quadruplets is 0.9129 

 ± 0.0059. There is little real difference in this respect between 

 the two sexes and the degree of correlation of both is of the same 

 order as that determined for the antimerically paired organs of 

 the same individual, 



2. The evidence here presented does not confirm the earlier 

 statements regarding the relative variability of the two sexes, for 

 there appears to be no sensible difference between males and fe- 

 males in their degree of variability or closeness of polyembryonic 

 correlation. 



3. Males and females also inherit equally strongly from the 

 mothers, showing that there is no sexual dimorphism in connection 

 with the armor and no sex limitation in the inheritance of armor 

 characters. The coefficient of uniparental correlation for both 

 sexes is very close to 0.5, a coefficient which is to be expected 

 in all cases of alternative inheritance.
