Does every human being have a unique set of DNA?

The correct answer to this question is – Yes. About 99.9% of human DNA is identical from one person to another. This makes a large portion of our DNA be the same repetitive sequences. The 0.1% left might sound insignificant to you, but the 0.1% makes the difference. It will amaze you to know that the human genome contains up to 3 billion base pairs.

This means 0.1% of the total human genome that is unique to a person is about 3 million base pairs. These three million base pairs, which make the difference, lies the genetic material that determines features unique to you. This includes your hair color, eye color, risk of certain diseases, risk of obesity, and so much more.
