Brief Combination Repeat (STR) Areas

Y-DNA assessment a particular gang of Y-chromosome Brief Combination Repeat (STR) markers. Just how many markers checked out because of the most DNA assessment companies can consist of a minimum of 12 so you’re able to possibly 111, which have 67 getting aren’t felt a helpful count.

More STR indicators, the better the expense of the test. If pricing are a life threatening grounds to you personally, then you can be interested in starting with a smaller sized number of indicators, right after which update later on in the event that warranted. Basically, an examination of at least 37-markers is recommended whether your goal is to try to see whether you arrive out-of a certain predecessor otherwise ancestral range. Extremely uncommon surnames could possibly get a good effects which have as low as twelve-markers.
