How Dna testing can find out more about your ancestry


Do you know people who are looking for their real parents or even real children? If no, then you have probably watched reality television shows or movies where people have spent their whole life looking for their real family. The process done to actually identify if a person is your real family is called DNA fingerprinting or DNA profiling. Nevertheless, this is not the only time that DNA profiling and fingerprinting is used. The process is also widely used in different fields like crime and investigations.

Your Genome will tell us more about what is DNA fingerprinting through their article below.

What is a DNA fingerprint?

DNA fingerprinting is a method used to identify an individual from a sample of DNA by looking at unique patterns in their DNA.


  • Almost every cell? in our body contains our DNA?.
  • On average, about 99.9 per cent of the DNA between two humans is the same.
  • The remaining percentage is what makes us unique (unless you are an identical twin!).
  • Although this might sound like a small amount, it means that there are around three million base pairs? that are different between two people. These differences can be compared and used to help distinguish you from someone else.
  • Minisatellites are short sequences (10-60 base pairs long) of repetitive DNA that show greater variation? from one person to the next than other parts of the genome?. This variation is exhibited in the number of repeated units or ‘stutters’ in the minisatellite sequence.
  • The first minisatellite was discovered in 1980. Read more here.

That is a lot of information about DNA fingerprinting. There are pieces of information about how the first DNA fingerprint is produced, how a DNA profile is used today, how DNA profiles are stored, and many more. We can now under DNA profiling and fingerprinting better. Now, let us read about six ways DNA profiling matters. DNA Diagnostics Center will tell us more about it.

6 Ways DNA Profiling Matters

DNA profiling is a technique developed and perfected over the last 25 years to uniquely identify individuals based on their DNA – the genetic material that is present in each of the billions of cells in our bodies. DNA is, for all intents and purposes, a sequence of “letters” that encodes the unique information that makes us human.

While the sequence of code is nearly the same in all of us, there are important differences in the DNA between individuals. These differences can be used by scientists to uniquely identify individuals through the highly accurate process of DNA profiling.

The power of DNA profiling to uniquely identify individuals is even greater than the traditional method of fingerprinting. More importantly, DNA profiling can unambiguously determine family relationships, such as paternity, which fingerprinting cannot do. Only in cases of identical twins – individuals that begin life with the exact same DNA – does it become difficult for DNA profiling to distinguish. However, even these can be distinguished in many cases with advanced techniques. Read more here.

DNA Diagnostics Center provided us with information on where DNA profiling is used and how important it is. So it is used for identifying criminals, exoneration and freedom, identifying remains in tragedies, establishing paternity, establishing family, and determining ancestry. For more information about how DNA profiling could help you find your birth parents, let us read the article written by Henry Louis gates Jr. and Jake Byrnes below.

Can DNA Help You Find Your Birth Parents? (Part 1)

“I am adopted and have NO clues about my birth except a sort of “fake” birth certificate from when I was born in Texas. No family name. No known blood relatives. Would the DNA test be a good option for me anyway? What will I learn about my family from taking a DNA test?” ~ Rita M.


Dear Rita,

The short answer to your first question is “yes, absolutely:” An adopted person can — sometimes — be fortunate enough to find the identity of their biological mother and father through one of the major commercial DNA tests available today. And the answer to your second question is “quite a lot.”

Let us explain what we mean by sometimes: if your biological parents or grandparents, brothers, sisters, or close cousins have already had their DNA tested, you will always be connected to them, and your relationship identified, by logging into your own privacy-protected account from the DNA company that tested you. We have to say sometimes because not everyone has had their DNA tested. But if every parent who put a child up for adoption had their DNA analyzed, that child would always show a connection to their biological parents in that same DNA database. We are a long way from reaching that goal but it is a noble one to which to aspire. Read more here.

There we have Rita writing and asking about how she could locate her family when she only has a fake birth certificate and she has no family name and no known blood relatives. So Henry and Jake explained to her what she could do about it. DNA profiling has already helped reunite many families before and it is amazing how this is done. It is really something that we should be thankful about because it has also helped solve crimes and that alone is a very important contribution.

Here Are the Different Things That Your DNA Can Reveal About You

Your genes are like the bricks that help to build the house. If they are strong the building will be steady but if they are weak then you take measures to strengthen them. It is for this very reason that many people have now started to opt to get a DNA test done that can help reveal a lot about the person that you are and also help you with means to overcome any traits that may need some extra precautions. Although, your genes may not be the only factor that is responsible for the person you are there are a few distinguishable traits that you may find in yourself that can be credited to the genes that you possess. In addition, you can also use your DNA to map out your family tree and find out more about your ancestors.

As your DNA is responsible for your entire genetic makeup it can reveal a lot about you and sometimes you may even find out something that is truly surprising.

Physical attributes that DNA can reveal:

Sex: This is one of the simplest traits of a person that can be identified from their DNA. If the DNA is comprised of an X and a Y chromosome then the individual is male while the presence of two X chromosomes indicates female.

Hair Color: your DNA can reveal the true hair color that you were born with. For example, if an individual contains 2 mutated genes that prevent the formation of pigment producing cells known as melanocytes then that individual is a natural red-head.

Eye Color: there are four genes that are responsible for the color of your eyes. Scientists can identify the individual’s eye color with a simple DNA test.

Personality traits that can be revealed with the help of DNA Testing:

It may be surprising but your DNA is also to some extent responsible for the kind of person you are. It can help to determine various personality traits such as

Body clock: whether you are a person who believes in early to bed and early to rise or if you are a night owl can also be determined by your DNA. The gene Per2 has been linked to individuals with advanced sleep phase syndrome whereas the gene Per3 is more likely to be found in those individuals who are night owls.

ADHD: The genes present in your DNA can also reveal whether you have Attention deficit hyperactivity disorder. This is a condition that is shown to be linked to the gene DAT1 having a genetic stutter.

Adventurous: There is a certain version of a gene that is present on the X chromosome that is most often associated with creating impulsive tendencies as well as thrill seeking traits in the individual.

Your DNA can also reveal a lot about your health:

The length of your life: there is a particular type of the Klotho gene that is known to be associated with the length of human life. The gene influences the various diseases such as stroke or cardiac diseases that are related to age.

Obesity: The FTO gene variant that is present in almost 50% of the population of UK is responsible for the individual who carries the gene to have 1.6% higher weight than those without the gene. There are also a few cases in which the individual carries 2 copies of this gene making them an average of 3 kgs more than the rest of the population.

Disease: your DNA can also reveal the possibility of you suffering from various diseases such as, Huntingtons, which is caused by a mutation in the Huntington gene; Breast cancer in women who have the BRCA1 or BRCA2 gene; Familial adenomatous polyposis, which is a type of bowel cancer in people who have a mutation in the APC gene; or Cystic fibrosis and many other diseases.

Your DNA can also reveal whether you belong to a special group of gifted children .


Orbot – The Greener Cleaner

Have you ever walked into an airport, hotel hallway or room, and smelt a dingy humid scent because the carpet had been recently cleaned? Was the carpet truly clean or was it still grey and dull in appearance? Are these signs of a healthy, clean, and safe environment?

Orbot was designed in mind to support a healthy indoor environment. Carpets will simply be clean, vibrant in colour, and dry within minutes. The system will eliminate the most common problems caused by other cleaning methods that lead to mold growth, mildew, volatile organic compounds (VOC), insufficient drying times, recurring stains, and safety hazards.

The unique Orbot low-moisture system uses 10 to 15 times less the amount of water opposed to water extraction methods. Therefore over-wet carpets will never be an issue. Wet carpets that are walked on will almost always resoil more quickly. This is because the chemicals and moisture act as a magnet, pulling dirt and debris back into the carpet fibers.

Eliminate Health Risks

Long drying time increases the likelihood that mold and mildew will develop, seriously jeopardising indoor air quality and potentially harming the occupants health. With longer drying times there is a greater possibility that gases and volatile organic compounds will be released into the air. This can cause allergic reactions and respiratory problems, especially for young children.

Simply put, what falls to the floor like common dust, pollutants and many things that we breathe, tends to stay on the floor until it is cleaned. Properly maintaining the cleanliness of the floors by using the low-moisture system will lead to improved air quality and a healthier indoor environment that can be seen, smelt, and felt to believe.
