Eye color in humans is primarily determined by genetic factors that influence the amount and distribution of melanin in the iris. The main genes involved include OCA2 and HERC2, which regulate melanin production. Higher melanin levels typically result in darker eye colors, such as brown, while lower levels can lead to lighter colors like blue or green. Environmental factors and evolutionary adaptations may also play a role in the variation of eye color across different populations.

What would happen if humans had no earlobe?
It is extremely common for humans to have no earlobe to speak of . . . it is hereditary just like eye color or skin color.
What is the difference between a dog eye and a human eye?
I think that the difference between human eyes & dog eyes is that all dogs are color blind but not all humans are color blind. We can see in color as dogs cannot.Yes this is the maindifference but I would like two point out that through dogs are color blind that they do indeedsee in color but they are missing a type of cone that humans have and they have way less. Dogs have a lot more rods then humans.
How do you have one eye one color and the other eye another color?
Having one eye of a different color is typically due to a condition called heterochromia, which is caused by an excess or lack of melanin. This can be either acquired or congenital. It results in one eye being a different color than the other due to variations in pigmentation.
Can a horse see color?
Animals, including humans, have "rods and cones" in the eye that allow them to see color. Horses have some, but not as many as humans, so it is believed that they see color, but pastels. These colors would be associated with food, water, and blood.
Are crickets colorblind?
This is dependent on which viewpoint one looks at this from. From a human viewpoint, crickets are indeed colorblind in that they cannot see certain colors that humans can see. However they can also see violet and ultraviolet wavelengths which humans cannot see. Crickets can see color, but not the color humans can see.
What is the default eye color?
The default eye color in humans is often considered to be brown, as it is the most common eye color globally. This prevalence is due to the higher levels of melanin in the iris, which not only provides the brown color but also offers protection against UV light. Other eye colors, such as blue, green, and hazel, are the result of variations in melanin production and genetic factors.
What color can humans not see and why?
Humans cannot see the color ultraviolet because our eyes are not sensitive to that wavelength of light. Ultraviolet light has a shorter wavelength than visible light, making it invisible to the human eye.
