Brief Tandem Recite (STR) Segments

Y-DNA evaluating a specific gang of Y-chromosome Short Tandem Repeat (STR) indicators. Exactly how many indicators checked out by most DNA evaluation organizations normally are priced between a minimum of several so you can up to 111, which have 67 being are not thought a helpful amount.

For people who checked-out 67 markers, yet not, and found an accurate (67 getting 67) fits having someone else, then there’s a 50% opportunity that two of you display a common ancestor within this several years and you can good 95% options the prominent predecessor is actually 6 generations.

The more STR indicators, the higher the cost of the exam. In the event that rates are a critical basis for you, you might be interested in starting with a smaller sized count away from markers, after which modify at a later date if warranted. Generally, an examination with a minimum of 37-indicators is advised if your purpose is to determine whether your arrive of a specific ancestor otherwise ancestral range. Really rare surnames can see a useful effects that have just 12-markers.
