MEASURE OF RESEMBLANCE OF FIRST COUSINS 



obtain a general average degree of resemblance between the ten types of cousins for 

 seven characters, we find for the whole seventy tables : 



Mean value '267 ± '008. Standard Deviation = -093 + -006. Accordingly we may 

 conclude that the average degree of resemblance of cousins lies between - 25 and "30, 

 say at '27.
