Answer:

0.1%

Step-by-step explanation:

Humans share 99.9. % of genome with each other but we are still unique when it comes to the remaining 0.1% of genome. Since human genome is made of 3 billion base pairs, 0.1% means that we have 3 million unique base pairs. This portion is used for techniques like DNA profiling. It is used for paternity test and also used to determine the culprit at a crime scene.

Short tandem repeats or STRs are combination of base pairs which are repeated a number of times and they are unique to every individual. STRs fall under 0.1% of unique genome. If STRs in two samples match at the same loci, they belong to the same individual.
