Consider the fact that eye color is inherited. This postulate put forward Johann Mendel, the Austrian biologist and botanist, who lived in the XIX century. According to his law, eye color inherited in the same way as the hair: if dark genes are the dominant colors, distinctive features (phenotypes) encoded them, take their superiority over the hallmarks of a lighter color.
Look at the color of their eyes and the color of the iris of the husband or wife. If you both have dark color eyes or brown, the baby probably will be born with dark eyes. Accordingly, the children of parents who have bright eyes, will also have light color eyes.
If you and your spouse eye color is different, then determine the color of the iris of your child according to the theory of dominant genes. For example, mom's blue eyes and dad is light green. Their baby might have blue eyes with probability – 60%, light green – 40%, as the blue color is dominant.
The most common eye color on earth is brown and rare green.
Don't panic if at birth his eye color doesn't meet your expectations or does not match the color of your eyes. The vast majority of children at birth have blue-grey or bluish-grey eyes. Around 6-7 months it becomes clear, what will be the color of the eyes in the future. Those children who have dark skin at birth, usually have dark grey or brown eyes. Eye color is determined by most of the parental genes, but even great-grandfather or great-grandmother can suddenly make a contribution.
Refer to the online programs on the Internet that offer to help prospective parents determine the color of the eyes of a child. To do this, specify the color of your eyes and the eyes of the partner, as well as the eye color of your parents and partner's parents, your brothers and sisters.
The calculator will make a calculation and give the probability of future color of eyes your child.
