 * Questions of science: Why Do People Have Different Eye Colours?**

Eye colour is genetic and we each receive our eye color based on our own family tree. However, each eye color is different for a reason, the darkness and colour of your eye is largely due to the amount of melanin pigment you posses. Melanin is a pigment found in both humans and animals, it is responsible for not only eye colour, but hair (or fur, feathers, scales - whatever that particular animal may posses) and skin colour as well. Typically speaking, the more the melanin, the darker your eye, hair and skin colour will be. Eye colors such as blue and blue/grey are becoming increasingly rare because these eye colors in particular require a recessive gene, meaning that the gene has to reoccur twice (from mother and parent) before it will be shown as your natural colour. The mere fact that the gene is recessive makes it especially difficult to occur when the gene pool is so diverse as it is today, it is quite likely that on parent will have brown eyes (which is a dominant gene) and overthrow the possibility of their child having blue eyes. The gene type you have (recessive or dominant) may also help you determine why you have the colored eyes you do.
