Mutation Rates
Mutation rates are those per generation, as estimated in Chandler (2006). The quoted estimated errors are typically +/- 15-20%. Alternative estimates from observed pedigrees are also available for some markers.
It appears that some trinucleotide markers may have much higher mutation rates at some repeat lengths than at others. For example, variation of the trinucleotide DYS388 is generally very slow in most haplogroups, when it takes the values 11-13. But there appears to be much greater variation and more rapid mutation in Haplogroup J, where it typically has values 14-18. Similarly the trinucleotide DYS392 is reported to be "fast" in haplogroups N and Q, where it takes values 14-16 which are rare in other groups.

Famous quotes containing the word rates:
“[The] elderly and timid single gentleman in Paris ... never drove down the Champs Elysees without expecting an accident, and commonly witnessing one; or found himself in the neighborhood of an official without calculating the chances of a bomb. So long as the rates of progress held good, these bombs would double in force and number every ten years.”
—Henry Brooks Adams (1838–1918)
