Sorry, much preoccupied with other things at present. Yes,i believe TiP takes recLOHs into account (though I wouldn't swear my memory is correct). Alas despite Diana's relatively clear explanation I still couldn't recognize a recLOH - I just don't Know if my project has any!

If you count each numerical difference as a single-step mutation, you will over-estimate the genetic distance between individuals. " My understanding is that the FTDNATiP calculator algorithm takes this into account. Is that so? Or, am I mistaken? -ralpht_/) ______________________________ PLEASE trim the amount you backquote in your replies to the minimum, especially if you subscribe in DIGEST mode. ------------------------------- To unsubscribe from the list, please send an email to Y-DNA-PROJECTS-request@rootsweb.com with the word 'unsubscribe' without the quotes in the subject and the body of the message
