Fingerprint Inheritance Conclusion
Posted: Sat May 04, 2019 8:43 pm
My daughter did her science project on Fingerprint inheritance. She tested 37 people (20 parents and 17 children). She took all 5 fingerprints on their right hand. Out of the 85 children's fingerprints, 72 matched one of their parents pattern type. My husband says because all 85 didn't match, then she didn't prove that fingerprints are inherited.
What can she do differently with her data? What is the threshold she should've used? This kid worked so hard, but we got off topic when we learned about how loops are more common, and arches are least common. I feel like she had too much information, and nothing concrete to say she proved it.
When asked what she thought couldn't have caused the 13 non matches, she said; 1. unclear fingerprint, 2. she could've miscategorized, 3. DNA comes from farther back than just the parents, they could be a match to a grandparent.
HELP! She is determined to submit it to the regional science fair, and I feel like i need to help somehow.
