My husband Greg and I have had our DNA tested. We used The tools that employs to compare details of family trees and shared DNA matches to help establish how we are related to others who have also tested at are quite useful but could be better. However, does not provide a chromosome browser.

A chromosome browser produces a diagram of where on your chromosomes you share DNA with your match. If you know how you and your match are related, you can deduce that you have both inherited that shared DNA from your shared ancestors. You can then attribute that shared DNA to those ancestors. When you don’t know how you are related, you can look at where you match and based on your analysis of who you inherited that bit of DNA from, you can predict how you are related. in effect does this calculation for you with their shared matches tool but doesn’t show the calculations in making its predictions.

The tools offered by, GedMatch and Family Tree DNA include a chromosome browser which does not provide. A chromosome browser gives you the detail of what DNA you and your cousin share.

One of the genealogical puzzles I sought to solve with DNA was the parentage of Greg’s great grandfather Henry Sullivan. I produced a hypothesis that he was the son of Matilda Sullivan nee Hughes. I need more data on how various cousins share DNA to show that Matilda Sullivan nee Hughes was indeed the mother of Henry Sullivan. The shared matches tool of is incapable of showing that descendants of Eleazar Hughes, Matilda’s first son are definitely connected to descendants of Henry Sullivan. A chromosome browser would help to show that these cousins do indeed share inherited DNA.
