Green eyes naturally occur in all races of people. Liqian, China is a hot spot for green eyes. There is a village in China called Liqian, in which two-thirds of all inhabitants today have green eyes and blonde hair. Green eyes and blonde hair are a rare combination.
Essentially, green eyes are unique. Most common in Western, Northern, and Central Europe, green eyes often point to German or Celtic ancestry. Currently, they can be found most often in Iceland, the Netherlands, Scotland, Britain, and Scandinavia.
So where did our green-eyed ancestors come from? Most origins point to areas around the Caucasus Mountains, which link Asia and Europe. That may help explain why so many different countries and continents have had green-eyed populations for thousands of years.
Iris color is determined by our parents' eye colors mixed with a little genetic lottery. Green irises have an uncommon melanin level — less than “truly” brown eyes, but more than blue eyes. This is why green eyes are so unique.
If the brown-eyed mother carried the green allele (bG), she could pass the green allele on 50% of the time, so when married up with the father's blue allele, they could have a green-eyed child.
The allele genes come in the form of brown, blue, or green, with brown being dominant, followed by green, and blue being the least dominant or what is called recessive. Given this information, you can determine what eye colors are dominant in the parents.
We found that green is the most popular lens colour, with brown coming in a close second, despite it being one of the most common eye colours. Although blue and hazel are seen as the most attractive eye colours for men and women they are surprisingly the least popular.
People with green eyes are more likely to have certain health issues. Green eyes are more prone to melanoma of the uvea, a type of eye cancer, than are dark eyes. The same is true for macular degeneration.
Twenty-nine percent of participants associated green eyes with sexiness, the top characteristic thought to be related to this color. Green-eyes was also thought of as creative (25 percent) and a little devious (20 percent). Being trustworthy and shy was also linked to green-eyed people.
There are plenty of blue-eyed Asians. This probably happens when the traditional blue-eyed allele comes into a family from a (possibly very distant) European ancestor. Blue eyes then resurface in a child generations later if they inherit the allele from both parents.
A couple's children can have almost any eye color, even if it does not match those of either parent. Currently it is thought that eye color is determined by about six genes, so you can imagine how inheritance of eye color becomes very complicated.
Genetics and Eye Color
The trait that is hidden is called recessive. Brown eye color is a dominant trait and blue eye color is a recessive trait. Green eye color is a mix of both. Green is recessive to brown but dominant to blue.
First, the answer is yes to both questions: two blue-eyed parents can produce green or brown-eyed children. Eye color is not the simple decision between the brown (or green) and blue versions of a single gene.
Yes. The short answer is that brown-eyed parents can have kids with brown, blue or virtually any other color eyes. Eye color is very complicated and involves many genes.
