The Human Genome Project has demonstrated that in humans of all races and nationalities approximately 99.9 percent of the genome sequence is the same, yet different individuals can be identified by DNA fingerprinting techniques. What is one primary variation in the human genome that can be used to distinguish different individuals? Briefly explain your answer.

Question

Accepted Answer

Everyone. Let's take a look at this question together, which of the following is a primary variation in the human genome that may be used to identify individuals. So let's take a look at the following answer choices to figure out which one is a primary variation in the human genome that we can use to identify individuals. So when we're talking about variations in the human genome, specifically a primary variation, the most revel in form of that genetic variation R S N P S or single nucleotide polymorphisms, which we can use to identify different individuals because they are useful for D N A fingerprinting method. And this is due to the fact that they are unique two and individual and they are also simple to find and compare among other individuals. And so that means that answer choice B single nucleotide polymorphisms or SNPs is the correct answer because SNPs are the most prevalent form of genetic variation and are useful for D N A fingerprinting methods because they are unique to an individual and simple to find and compare to other individuals so that we can use them to identify different individuals. So answer choice B is the correct answer? I hope you found this video to be helpful. Thank you and goodbye.
