    we have genes that determine our fingerprints...i don't know if someone could have a genetic defect that would change it. It is a continuous trait with multiple alleles (i am pretty sure), so i don't know how likely that would be. That is a good question...

    well, i just did a little google work, and found a disorder called dermatopathia pigmentosa reticularis, which is an extremely rare genetic disorder, and one of the symptoms is no fingerprints.

    Genes? The way I understood it, the ridges in the skin that form fingerprints is formed by embryonic fluid. *shrugs* Not 100% sure, can anyone clarify?

    genetics determines the general pattern of ones fingerprints, but the microenvironment in the uterus determines the fine details. thats why identical twins will have similar but not identical finger prints ;)

    everyone has a unique fingerprint. its like DNA as it can be compared, collected and used to slam suspects. However, DNA sometimes can have more than one person, for example father and son but fingerprints are different for everyone.

    fingerprint have only been know to be an identity aid for summit like 300 years, but i dont recall someone not having fingerprints, you can alter them by cutting skin and replacing in diffrent places, but that would be extreamly painfull!!!

    im confused by what you mean here. a father and son don't have the same dna, the son has 50% of the fathers dna and 50% of the mothers. only identical twins have the same dna.
