If there is there a gene for blue eyes, what number is that gene?

Question:I have blue eyes, but my birth Mom's were brown so therefore statistically it is almost 100% likely my Dad's eyes were blue. So can the eye color be found in a Y-Chromosome test? If there is there a gene for blue eyes, what number is that gene?

Eye color is not sex-linked, so it is not on the X- or Y-chromosome (men have one of each), and could not be found with the DNA test currently available to the public. There is more evidence than previously thought that eye-color is governed by more than one gene (accounting for eye color such as hazel or green); these also are not necessarily located on the Y chromosome, or even on the SAME chromosome. The human genetic "map" is complete, but we do not yet begin to know all the functioning of every gene.

The 3 eye color genes that are presently known are: EYCL1 (gey), the Green/blue eye color gene, located on chromosome 19; EYCL2 (bey1), the central brown eye color gene, possibly located on chromosome 15; and EYCL3 (bey2), the brown/blue eye color gene located on chromosome 15. We do not yet know what these genes make - what proteins they produce, or how the proteins produce eye colors. Eye color at birth is often blue and later turns to a darker color. Why eye color can change over time is not known.

Remember that genes are not numbered, but only labeled; human chromosomes are numbered 1 through 46, and a chromosome has many thousands of genes on it that govern every possible trait in in the human organism.

It's number 11
