For an individual to understand the difference between these tests is very important, it could help an individual to know in which ways are the DNA organized before the process is performed or started. The DNA sample is basically collected from long stretches which are called chromosomes. Each and every individual typically has a total number of 46 chromosomes which means it has 23 pairs.
