DNA analysis

 

In recent years DNA analysis has become a popular tool with genealogists.  The scientific details are far beyond the scope of this document.  Yet it is necessary to understand the concept of DNA in order to see the potential value and the usefulness to genealogists

DNA is a molecule that contains instructions to your body.  Think of a mile-long ladder where each rung is an instruction. Many instructions are common to all people, and some are different. Your size, your sex, the color of your hair are determined by the DNA molecule.  Each child inherits DNA from both parents.  And this is different than any other person.  The similarities in the molecule reveal  your parents, their parents, grandparents, and further back. Similarly, each ancestor has contributed to your DNA.

Many technical articles about DNA are available.  The complexity of the molecule is illustrated below.  The internet will explain this in whatever detail you want/

Half of your DNA comes from each parent, on quarter from each grandparent, and one eighth from each grandparent.   You and your cousin have a common grandparent and the number of common DNA elements reveal this relationships

There are several private companies that will test your DNA and provide a list of individuals who share your DNA.  We have used this to find several relatives starting with second cousins.  Second cousins are descendent from the same grandfather.  50% of your DNA comes from each parent, 25% from each grandparent, and 12% from each great grandparent.

The DNA might identify your susceptibility to physical or mental problems.  While that information may be useful to you. This information may also influence your suitability for certain careers.   This introduces legal issues so DNA analysis must be protected.

I have paid two companies for a DNA analysis.  A major function of the DNA analysis iOS identification of individuals that are related.  Second function is to identify physical or mental features that are common in your DNA related group.For illustration, some of that information is copied here.  This is a part that identifies features common to others in my DNA category (Haplogroup)

Carrier Status Reports 0 highlighted reports of 44 reports available


Learn whether you have specific genetic variants that may not affect your health, but could affect your children’s health.Consider talking to a healthcare professional before making any major lifestyle changes or if you have any concerns about your results.

If you see “Variant not detected” for a Carrier Status report, it means you’re not a carrier of the tested variant(s). Keep in mind that while our Carrier Status reports cover many variants, they don’t include all possible variants associated with each condition. So it’s still possible to be a carrier of a variant not included in our test.
