What causes blue eyes?
The colour of our eyes depends on how much melanin is present in the iris. Blue eyes get their colour the same way water and the sky get their blue colour — they scatter light so that more blue light reflects back out. … The front layer of the iris (called the stroma) is made up of overlapping fibers and cells.
Why do Aboriginal have blonde hair?
The common occurrence of blond hair among the dark-skinned indigenous people of the Solomon Islands is due to a homegrown genetic variant distinct from the gene that leads to blond hair in Europeans, according to a new study from the Stanford University School of Medicine.

Are blue eyes from inbreeding?
Does inbreeding really lead to deformities and diseases could inbreeding actually be a good thing? For example, the gene for brown eyes is dominant and so having just one of these in a pair will result in your eyes being brown. However, the gene for blue eyes is recessive so you’ll need both of them to get blue eyes.

Why is red hair so rare?
Red hair is associated with the gene MC1R, a recessive and somewhat rare gene that occurs in only about 2 percent of the world’s population, according to the National Institutes of Health.
