What do Unit Evolutionary Periods have to do with it? One is a time unit and
the other is a description of the variability (or non-variability) of a specific
locus. The definition of UEP is "The time in millions of years for 1%
divergence to occur in the make-up of a particular protein common to two
species, or in the base sequences of the corresponding genes."

If you mean SNPs can be "synonymous," that is, can represent changes in
nucleotides that do not affect the structure of the protein they code for, yes,
of course. When a SNP produces a change in the coded protein, it's called
