How does a DNA chart help to understand DNA results?

The chart can help you narrow down which possible relationships to focus on in your research. As you can see from the centimorgan chart, a centimorgan range of 575 to 1330 could mean the DNA match is a first cousin, half aunt, or even a grandparent.

How do DNA charts help in understanding inheritance patterns?

The chart is great for directing your research into the possible connection but there is no substitute for documents and solid family tree building. As a tool, DNA centimorgan charts are without question very valuable. A combination of DNA and document evidence can be all you need to confirm a family relationship.

What benefits can a DNA centimorgan chart provide?

Since DNA is inherited randomly, even a sibling may share more, or less, DNA with a relative than you do. A centimorgan can only tell you how much DNA you share with a genetic relative. There may be multiple genealogical relationships that can share the same amount of DNA.
