    According to the not comprehensive statistics, the number of people with blue eyes is more than those with brown eyes. However, we could change the color of eyes by using the colored contact lenses to show the great attraction and charm. Only clicking on the online store can we get the colored contact lenses.

    Well, it seems that you are quite interested in this particular field right? So, as far as I know, up to know, few people have done some research on this so we can only tell you from the distribution and proportion of races. Generally speaking, white people are heavily outnumbered by other races, especially in Africa, Asia, and South America, so, brown eyed people are supposed to be dominant over blue eyed people.

    Brown eyes are dominant. Now that you are interested in this matter, I will tell you more about it. Suppose that the gene of the brown eyes is expressed in A while the gene of the blue eyes in a. The genotype of person with brown eyes can be AA or Aa while the genotype of person with blue eyes can only be aa. When a person with brown eyes marries a person with blue eyes, their baby can be brown eyed or blue eyed as long as the genotype of person with brown eyes is not AA, otherwise, their baby can only be brown eyed with the genotype Aa. Also, a person with brown eyes marries a person with brown eyes, their baby can be blue eyed under the condition that both of the two person own the genotype Aa. As inferred in this way, blue eyed person marries blue eyed person, their baby can only be blue eyed.
