In 1907, Charles and Gertrude Davenport developed a model for the genetics of eye color. They suggested that brown eye color is always dominant over blue eye color. This would mean that two blue-eyed parents would always produce blue-eyed children, never ones with brown eyes.

The allele for brown eyes is the most dominant allele and is always dominant over the other two alleles and the allele for green eyes is always dominant over the allele for blue eyes, which is always recessive.

Throughout the world, 79 percent of people have brown eyes and 5 percent have hazel eyes. These two colors are often considered the same color, but they are two distinct hues. The iris of your eye is the part that has color. There are genes that work to determine whether your eyes are brown, hazel, or another color.

But the high prevalence doesn't mean all brown eyes look the same. There is plenty of variation in the appearance from person to person, and there are even health advantages to having brown eyes (more about that later).

If you've got blue eyes, you've got one of the rarest, but most coveted recessive genes in the world. In fact, only about 17 percent of the world's population has blue eyes. In contrast, more than 50 percent of the global population is believed to have brown eyes.

Blue eyes have a low level of pigment present in the iris. ... Brown is the most common eye color. Individuals with brown eyes have more melanin present, and over half of the people in the world have brown eyes. Gray eyes may be called “blue” at first glance, but they tend to have flecks of gold and brown.

Black + Blonde = Brown! So all in all the answer to your question is neither! Blonde hair, brown hair, blue eye, browns eyes … none of those traits are dominant or recessive as they are not due to a single gene.

The brown version of gene 1 is dominant over the blue one. ... The way geneticists represent these two different versions of this eye color gene are B for brown and b for blue (the capital letter is always the dominant, the lowercase, the recessive). So you will have brown eyes with either BB or Bb and blue eyes with bb.

Since brown eyes are dominant, the mom can have either one brown (B) and one blue (b) version of an eye color gene or she can have two browns. As geneticists like to say, she can be either Bb or BB. To make things easier, we will say that she is BB (both genes are the brown version).

Since blue eyes are genetically recessive, only 8 percent of the world's population has blue eyes. While blue eyes are significantly less common than brown eyes worldwide, they are frequently found from nationalities located near the Baltic Sea in northern Europe.

Only 8 Percent of the World's Population Has Blue Eyes Since blue eyes are genetically recessive, only 8 percent of the world's population has blue eyes. While blue eyes are significantly less common than brown eyes worldwide, they are frequently found from nationalities located near the Baltic Sea in northern Europe.

1 The evidence suggests that all people with blue eyes carry this same variant. So the parts of the world where descendants of that founder individual are most common have the highest frequency of blue eyes; where those descendants are rare, darker eye colors are the dominant eye color.

People with blue eyes tend to have greater light sensitivity. Night vision is often better among people with blue eyes. A genetic mutation is responsible for blue eyes. People with blue eyes are more likely to have red eye in photos.

Men with brown eyes were rated consistently as more dominant than blue-eyed men. No such effect of eye-colour was found for the photos of women. Eye colour also bore no association to the attractiveness ratings. Next the researchers used Photoshop to give the brown-eyed men blue eyes and the blue-eyed men brown eyes.
