DNA testing is something which everybody is curious about, no matter who you are and where you are in life. Many celebrities have invested time and money into taking DNA tests and finding out about their ancestry.

Actress Liv Tyler and her rock star father, Steve Tyler, learned through their testing that they have African-American roots. Oprah Winfrey discovered, through her own testing, that she had Native American DNA as well as East Asian DNA.

This just goes to show that no matter who you are or what heritage you think you might have, DNA tests can unveil some surprising revelations.

An individual may also be curious whether they are distantly related to a celebrity in history. This is what makes DNA tests so appealing – you just never know until you do your research!

So what can DNA testing really reveal?

Your Genealogy and Family Tree

It's only natural to wonder who your ancestors were and where you came from. Your DNA can reveal what percentage of different countries you may have in your lineage. For example, you could have been born and raised American only to discover you are also 20% Italian.

Actress Jessica Biel recently began researching her family tree after being told nothing other than that her family had been German. Uncovering her lineage, she discovered hints at a Jewish background rather than German like she had initially thought. She proceeded to take a DNA test and discovered she was 8% European Jewish.

DNA tests really can unveil unexpected things. You can try the cheapest DNA testing kits of 2019 to find out about your own genealogy.

There are services which offer to compare your DNA to the DNA of others held on record in order to connect you with relatives you might not have known you have around the globe.

Health Issues

A DNA test can reveal a lot about your health. Your DNA can be studied by a health professional in order to identify any variations which may be linked to particular health conditions. They can also be used to check whether you have any hereditary diseases if you begin to show symptoms, as the genetic testing can confirm whether that is the case or not.

Home DNA kits can determine whether you're more likely to develop certain types of diseases or conditions.

Studies have also shown that DNA can indicate whether you're more likely to lose or gain weight easily. Your size and weight could very much be determined by your genes.

Your Biological Parents

If you're adopted, or perhaps only know one of your birth parents, it is possible to use your DNA to discover your biological mother and/or father. Paternity tests are very common in order to trace birth fathers, and once found, additions to the family tree can usually be discovered based on the biological father's surname and tracing it back.

These tests will provide DNA matches within a database to uncover the family you didn't know you had, including your truth birth parents. It's a good idea to try as many DNA tests as possible for this one, to have access to a more extensive database of results.

Identifying Mysteries

Back in 2012, a set of remains were discovered in a car park in the city of Leicester in England. Through DNA testing, they were able to be identified as the remains of one of the most famous kings of England, Richard III.

On initial discovery, experts could not be sure the remains belong to the King until DNA testing confirmed it.

DNA can stand the test of time, preserved for thousands of years if stored correctly in cold, dry places (such as beneath a car park in England!).

These sorts of discoveries made through DNA can shape history and serve to prove (or disprove) facts which historians and experts thought they knew.

Which just goes to show the power of DNA and the sorts of information you can uncover about yourself through DNA testing.

Problems in Offspring

Using DNA samples taken from both the mother and father, scientists are able to determine whether an unborn baby has any abnormalities in its chromosomes, which may result in a genetic disorder once born. This could include whether a child will have Down Syndrome, for example.

This field of DNA testing is expanding with further research, in the hope of being able to uncover signs of further conditions such as developmental delays and learning disabilities such as autism and others.
