Mutation Question

[Jim Honeychuck]

Do the STR values of markers mutate up, down, or in either direction. Of the six members of my project, 3 of us are 38 at CDYb and the other three are 39. Is there any way to know which value is the mutation?

Many thanks!

Either direction.

In general, the most frequent value is thought to be the pre-mutation one. Since you don't have a very large sample, try looking in places like www.Ysearch.org.
