Abstract: | Two simple methods for estimating the numbers of synonymous and
nonsynonymous nucleotide substitutions are presented. Although they give no
weights to different types of codon substitutions, these methods give
essentially the same results as those obtained by Miyata and Yasunaga's and
by Li et al.'s methods. Computer simulation indicates that estimates of
synonymous substitutions obtained by the two methods are quite accurate
unless the number of nucleotide substitutions per site is very large. It is
shown that all available methods tend to give an underestimate of the
number of nonsynonymous substitutions when the number is large.
