eye color is not a very reliable or accurate method to use when attempting to determine paternity of a childand that
eye color usually starts out much lighter at birth, and becomes its true color in 1 or 2 years after birth. Variations can also occur randomly.
BIT's eyes started out gray, at different points in time they seemed blue, and some other times green. Now they are finally brown, like Mommy's and mine.
GeneTree also offers a free home DNA collection kit and DNA paternity testing services. But a couple of other interesting pages on their site are the blood type calculator and the conception calculator chart.
