People With Blue Eyes

West people usually have this blue eyes, but not all of them have blue color eye live on an island. No body can see his own eye color, they just know from others. Any history about this phenomenon, an islander who have figured out the color of their own eyes then leave the island, and the rest stay. Everyone can see everyone else at all times and keeps a count of the number of people they see with each eye color (excluding themselves), but they cannot otherwise communicate. Everyone on the island knows all the rules in this paragraph.

The special pigment has happened on this eye color, eye color is a polygenic phenotypic character and is determined by the amount and type of pigments in the eyes. Humans and other animals have many type phenotypic variations in eye color, its can be blue, brown, gray, green, and black.

Eye colors can range from the most common color, brown to the least common, green. Eye color is an inherited trait influenced by more than one gene. These genes are being sought using association to small changes in the genes themselves and in neighboring genes. These changes are known as single nucleotide polymorphism or SNPs. The actual number of genes that contribute to eye color is currently unknown, but there are a few likely candidates.
