Human Genetic Reconstruction

[devond]

Hi! In genetic splicing, a gene within the DNA double helix can be replaced with another, right? If this was done to human genes, could a physical difference be detectable on the person? For example, if a person's gene for eye color was replaced, would the person's eyes eventually, and noticeably, change color? If so, how long would the transformation process take? Thank you!

In Europe mosts baby's have blue eyes when they are born. But that color can change withing a couple of months.
I'm not quit sure what causes this but my gues would be melanine. If so this "transformation" should go with the same pace like the darkning of your skin. Withing hours yours eyes would become darker, but it would take (much) longer to make them lighter (blue).
I hope it's not a bad gues
