1. Fingerprints
Are they inherited?

2. Question:
Are Fingerprints created randomly or are they influenced by genetics?

3. Test:
How to compare fingerprints of family versus un-related people.

4. Variables Independent: fingerprints of relatives and friends
Dependent:pattern of fingerprints
Controled:fingerprints and people tested

5. Hypothesis
If I compare fingerprints then my relatives will have a closer pattern to mine than un-related people.

6. Conclusion
My conclusion is that the person related is closer because of the genetic system of a family.
