For the competition, I was planning on doing a paper an research related to genetic disorders and use some family members as subjects. But, DNA testing is really really expensive and I'm afraid I won't find anything so it'll have been a waste. Does anyone have any ideas or sites with ideas or studies that I can get inspired by?
I like chemistry, biology, and neurology, and unfortunately, have limited resources. I'm in need of guidance, any information will be helpful.

Thank you
