Background
What is Genetic Genealogy
Genetic genealogy is using DNA test results from ancestry.com, FTDNA, 23andMe and/or MyHeritage, in conjunction with traditional genealogy research to help identify your biological parents if you were adopted, and to help you identify and solve misattributed parentage, and other brick walls, in your family trees. Genealogy DNA testing can be used to enhance your family tree, confirm or refute family tree lines, and correct misattributed parentage. For adoptees, your DNA results can be used to fill in the family tree lines of your unknown parentage.

Genealogy vs Geneology vs Geneaology
A Common Misspelling of "Genealogy"
People frequently misspell "genealogy" as geneology, or even geneaology. And likewise, genealogist is sometimes misspelled as geneologist or geneaologist.
Most of us learned early on that the suffix "-ology" means "the study of", so it makes sense that the study of something relating to genes would be geneology or geneaology.
The correct spelling is genealogy, with the root of the word coming from the Greek word genea, meaning generation, family or race. And the ending does indeed mean the study of, it just doesn't have the connecting "o" before "-logy". Hence, genealogy rather than geneaology or geneology.
When you are searching for a family history on the internet, you might want to try alternate spellings of genealogy. For example, if you are searching for a Leitch family history, in addition to Leitch genealogy, you might want to search also for Leitch geneology and Leitch geneaology.
