Your DNA

Your DNA contains a unique set of instructions that provides the information to build you. At the DNA level, all humans are 99.9% identical. Each person’s unique identity comes from the 0.1%, or one one thousandth, of our DNA that is different. Most everyone has heard that every person inherits half of their DNA from each parent. Importantly, what we inherit are these DNA differences.
