Yes. Family Finder is able to tell a full sibling from a close cousin. Half siblings and first cousins, however, are harder to differentiate as they share roughly the same DNA in common. More distant cousins, such as 2nd cousins [...]
The microarray chip used for Family Finder tests about .024% of your autosomal DNA.
Yes. Men and women inherit autosomal DNA the same way. Therefore, the Family Finder test will detect matches to your relatives regardless of their biological sex.
The Family Finder test provides sensitive information about relationships. Therefore, thought must go into presenting matching results to all project members and to the general public. Before sharing, contact the relevant project members. Please be sure they are comfortable with [...]
The Family Finder program declares a DNA segment to be Identical by Descent (IBD) if it contains at least 500 matching SNPs (Single Nucleotide Polymorphism) in series. Note: This has not changed with the conversion to the Illumina Omni platform.
The Family Finder program determines relationships for up to five generations. We may return data and matches that are more distant. We established the confidence interval based on the level of quality to which Family Tree DNA customers deserve and expect.
Family Finder detects your near and distant cousins by comparing your autosomal DNA with that of other Family Tree DNA customers. If two people share identical segments of DNA, they may share a recent ancestor. When the Family Finder program finds matching [...]
The Family Finder test works by comparing your autosomal DNA to that of other people in our database who have taken the test. The program calculates your relationship with a match based on sharing linked segments of DNA. Any two [...]
For the program to consider two people a potential match, the largest matching DNA segment between two people must be at least 5.5 centiMorgans (cM) long.* The program then uses additional matching segments to confirm the relationship and to calculate [...]
No. Only our customers who order the Family Finder test or transfer through the Autosomal DNA Transfer product and opt in to matching will be available to match.
No. You may order our autosomal Family Finder test, mtDNA tests, and Y-DNA tests separately.
Family Finder results are usually completed about four weeks after we batch the order. At times, lab volume and other factors may cause that window to expand to six weeks. If it is necessary to send a new sample collection kit, you [...]
Judaism is a religion and not an attribute definable by a DNA mutation, but we can give you hints about having Jewish ancestry by comparing your Family Finder results to those of known Jewish ancestry in our database. myOrigins results [...]
Yes. Family Tree DNA would like every Family Finder Project to be a success. We ask that you consider these guidelines for planning and setting up Family Finder Projects.The focus couple should be between four and seven generations in the [...]
The Family Finder test has many uses within a surname or paternal lineage project. It helps to, Bring into your project men and women who are related but lack a male cousin with the corresponding Y-Chromosome DNA to test. Determine [...]
Yes. The actual genealogical relationship between you and your cousin may be closer or more distant than the relationship range. For example, the actual relationship might be 4th cousin twice removed.
If you use a third party tool, it is natural for there to be minor differences for the myOrigins results due to either different methodologies or different population sets.
The Family Finder Group Report page allows you to evaluate members according to information they have entered about their autosomal ancestry and to view their matching DNA segment data. The data columns are: Kit Number: This is the project member's kit [...]
The Family Finder Group Matrix page allows you to select up to 20 people and compare their Family Finder relationships in a grid (matrix). Options are: Group Members: These are project members who have Family Finder test results and are [...]
It is not unusual for the relationship to be undetected. Most Y-DNA67 exact matches are related within six generations. That is 4th cousins. Family Finder test will detect a relationship between only about half of all 4th cousins.
