QuASTLER (5) have estimated the error rate per cell per generation to be some 

 10-1 tQ jo-2 times the spontaneous mutation rate per cell generation (10^* to 

 10~i^). Taking this to mean that 



Piii) = q^{\-p) and p^ij) = p ^ \Q~^ (i ^j) 

 we see that 



/'^(01og2/7,(0 = +log2(l -p) ^-p = -10-6 



p,(j) log^Piij) = -6 X 10-« log2 10 ^ -10-5 (18) 



Because of the discussion given above this term in equation (13) may be neglected. 

 Equation (13) gives the value of {dHjdX) at the values of /?/;) corresponding 

 to Hg^. Let these values be plij). 



dH 



= J{X)[H, -H, + 12 P{i) log2 p'm ( ' 9) 



dH 



The coefficient of /(A) will be a constant so that — 



dl 



will behave as a function 



Ha 



of X like J{X). This result will be needed in my article in Part V.
