Are blue eyes caused from inbreeding?

However, the gene for blue eyes is recessive so you'll need both of them to get blue eyes. This is important as certain congenital defects and genetic diseases, such as cystic fibrosis, are carried by recessive alleles. Inbreeding stacks the odds of being born with such conditions against you.

Did Neanderthals have blue eyes?

Fair skin, hair and eyes : Neanderthals are believed to have had blue or green eyes, as well as fair skin and light hair. Having spent 300,000 years in northern latitudes, five times longer than Homo sapiens, it is only natural that Neanderthals should have developed these adaptive traits first.
