I spent the five happiest years of my life in a morgue. As a forensic scientist in the Cleveland coroner’s office I analyzed gunshot residue on hands and clothing, hairs, fibers, paint, glass, DNA, blood and many other forms of trace evidence, as well as crime scenes. Now I'm a certified latent print examiner and CSI for a police department in Florida. I also write a series of forensic suspense novels, turning the day job into fiction. My books have been translated into six languages.
I'm sorry but that can, and has, fill several textbooks. There's just no way for me to summarize it in a paragraph.
Usually in forensic science or any kind of natural science. If you want to go to into drug testing or toxicology, major in chemistry. If you want to do DNA analysis, then biology or biochemistry.
Your nuclear DNA is the same in the skin cells holding your hair in place, your saliva, your blood, your skin, your bone marrow etc. Your friend's DNA is of course different from yours, but the same in their saliva, their blood etc. The criminals probably threw someone else's hair around the crime scene so it wouldn't match them.
A good knowledge of chemistry is helpful to be able to understand why certain processes work the way they do. We use math to mix reagents and calculate angles in bloodstain pattern interpretation. Any knowledge can be helpful because we deal with every kind of person, job, situation, and object there is.

Is bottle service worth the money, or is it a total scam?
All the interesting, different, bizarre stories that make up the crimes that have happened that we have to investigate.
Sure, because fingerprints will have ridges and gloves will not.
Why does this sound like a homework question?
