Well, sort of.

Several ways. First, you can simply look and see which markers
have the biggest "spread" of values. Exceedingly roughly,
the bigger the spread the faster.

Second, you can read a scientific paper
(actually a presentation at a conference) in which they
describe a better way using graphs of marker mismatches.
They explain how at http://smgf.org/ASHG2004-4.pdf

However, you don't have to "do it" ... they have, and
I have. The relative rates are quite well determined.
The values in that presentation are almost certainly very good.
For relative values, that is.
