Sue: In the Kayser et al. article on father - son pairs, there were almost two "gains" to one "loss" (10:4 ratio) overall for 8 markers of the 15 markers tested (but one was a two step mutation loss). In other words, probability wise, mutations are more likely to be up one repeat than down one repeat.

Is there any data on the relative probablity of positive vs. negative
mutational changes? I know it's more likely to gain a repeat than to lose
one...but is there any comparative data?
