Finding the similarity ratio between two different parts of the human body

Question

[İrem]

What do you think is the most accurate method to find common or highly similar genes in human face and fingerprint?

Answer 1

There may be some disagreement on this issue, but I think human face is not an organ. Fingerprints are most definitely not an organ. It is unlikely that you will be able to find a gene expression dataset for either one of them, let alone both.

I think your idea is squarely in the category of those that sound good in our head, but are impossible to do in practice. Even if it could be tested, I don't think it would work. There are many people with similar facial structures (like between parents and children, or between siblings), yet I don't think there is any correlation between their fingerprints. Specifically, even identical twins have non-identical fingerprints.

well there is one approach is to utilise genome-wide association studies (GWAS) to uncover genetic variations related with face traits or fingerprint patterns. GWAS include studying the DNA of a large number of people to uncover common genetic variations that are statistically related with a feature of interest, such as height, eye colour, or facial shape.

The way I see it, here we are not looking for associations between genes and a single-feature trait related to either face of fingerprints. If my guess is correct as to the nature of this question, the OP is looking to connect fingerprints to more than just a facial shape or eye color. Cool idea to be sure, but is it practical?

Let's assume that 5-10 features identify fingerprints at least somewhat uniquely, and that the same is true for facial features. I think these are conservative assumptions. Is it likely that there are statistically significant connections between each feature combination and genetic variations? I think not, despite this being a theoretically sound approach.
