Answer 1

So, scientists have discovered **at least** 16 genes that contribute to eye colour. They are pretty sure there’s more.

Best I can remember, one is for melanin production (which affects how brown your eyes are), and so is another, and a third is the consistency of the goopy stuff in your eye. Changing the consistency of the goopy stuff changes light refraction which changes what we see when we look at a persons eyes. Cannot remember what the others are, but long story short – there are 16 different genes all having an impact. This gives us the huge variation from grey to blue to green, Hazel, brown and dark brown.

It is definitely not as simple as blue being recessive and brown being dominant.
