I would avoid using the term
I would avoid using the term "nowadays" in scientific writing. Rather you could say "Presently" "At thhe current time" or some variety of that.
I would revise this sentence:
I would revise this sentence: "By doing this, it allows for people" to say something more specific. For example, instead of saying "by doing this" you could simply say, "genetic investigtions allow for people to...". This would make the paragraph sound more consice. Other than that, nice job!
In the first sentence it
In the first sentence it should be "identify" instead of "identifies" since the subject is plural. Also I would revise the last sentence and say "currently many genetic tests exist..." rather than "currently it exists many genetic tests." It looks good though, over all!
