Fingerprints are one facet of a person's phenotype, so yes...plus or minus environmental variables.
That's my guess also... I'm just saying on that basis that maybe they are not part of the DNA programming
So your doubt is essentially a hunch?
Anyone for a PhD in this?
Fingerprints are formed in the womb and are influenced by the baby's movements and growth, so even identical twins have unique fingerprints.
Make your next question on phenology ... that could get interesting :)
