William Howard devised a simple method for taking two ydna 37 strs and computing a rough estimate for the number of years ago that their most recent comman male ancestor lived. (See his paper deriving the RCC timescale at "https://jogg.info/wp-content/uploads/2021/09/52.013.pdf".)
It is simply a scaling of the ordinary pearson correlation coefficent So, you can take your 37 ydna str and compare it to a potential relative's 37 ydna str and get Howard's estimate for how far back before your respective trees shared a male ancestor. |
