Question

Answer 1

The odds of two people having identical DNA are vanishingly small. If blood, or any part of a body including saliva, semen, hair and pretty much anything else are recovered from a crime scene the DNA can be compared to a suspect's DNA (or a pre-existing collection of DNA samples). If they match, it is pretty conclusive evidence putting a person at a crime scene.

It is also possible to deduce the likely DNA sequence of a person from the DNA of parents or other relatives. The result of this deduction is very helpful to establish paternity in claims for child maintenance etc.

Answer 2

It seems odd that you're doing your senior project on this topic and don't know what DNA evidence is, but okay...

Ten minutes isn't a long time when it comes to a presentation, but consider talking first about the evolution of DNA evidence since it was first used in the past 10-20 years, and then maybe you could talk about The Innocence Project (a team of people who evaluate death penalty cases that were tried when DNA evidence wasn't available -- many people have been set free as a result) and show how much things have changed and how important DNA can be to a person's guilt or innocence. Since you only have 10 minutes, everything will be pretty abbreviated and so it shouldn't be too hard to put together a presentation with that stuff. Good luck.

That’s a great question. some look to have confidence that DNA is actual, yet that technology can not clarify the way it replace into made, their next bounce is it replace into created by skill of a writer. They ignore on the subject of the reality this is shows relationships between species. i desire somebody who's professional death penalty and a creationist extremely does answer from their attitude. I’d have an interest to comprehend additionally.
