Eye Color and Paternity.

Determining paternity based on eye color dates back to the 19th century. Based on the work of Gregor Mendel, scientists began unlocking the secrets of inherited traits. Theories about genes and human development eventually led great minds like Watson and Crick to unravel the DNA double helix model, paving the way for modern geneticists to sequence the entire human genome in 2001.

The IDENTIGENE Eye Color Paternity Test demonstrates how eye color and inherited trait theory is used to determine paternity.

Instructions Enter the eye colors for Biological Mother, Child and Alleged Father (if the Biological Mother is not known, select 'Unknown' from the list). Click the "Show Results" button to see an instant paternity analysis based on the information provided.

Biological Mother Child Alleged Father Select... Unknown Light Blue Blue Blue-Green Green Hazel Light Brown Brown Dark Brown Select... Light Blue Blue Blue-Green Green Hazel Light Brown Brown Dark Brown Select... Light Blue Blue Blue-Green Green Hazel Light Brown Brown Dark Brown

Of course, the IDENTIGENE Eye Color Paternity Calculator does NOT replace a DNA Paternity test. While eye color can be an indicator of paternity, it is not consistent enough to be relied on for definitive results. An IDENTIGENE DNA Paternity Test provides the most valuable infomration for those with questions only DNA can answer.™

EYE COLOR HISTORY

Eye color follows a polygenic inheritance pattern, and is probably governed by 6 or more genes. Generally, these genes express themselves as one of 8 different eye colors. "Dark" is dominant at each of the 6 genes. The more dominant alleles present, the darker eye color appears. The following chart illustrates eye color inheritance theory:

0	1	2	3	3-4	4	5	6

Eye Color inheritance theory estimates paternity based on the assumption that lighter-eyed parents cannot have darker-eyed children. Consider the following examples:

- 2 'light blue' eyed parents cannot have a 'blue' eyed (or darker eyed) child.
- 2 'blue' eyed parents can have a 'Blue-green' (or lighter) eyed child, but not hazel or anything darker.
- 2 'blue-green' eyed parents can have a 'light brown' (or lighter) eyed child, but not brown or anything darker.
- 1 'light brown' eyed parent and 1 'blue-green' eyed parent can have a child with any of the possible eye colors.
- 2 'dark brown or black' eyed parents can have a child with any of the possible eye colors (but it is unlikely they will have a light eyed child, such as light blue or blue).

Eye color often appears much lighter at birth, and becomes its true color in 1 or 2 years after birth. Variations can also occur, randomly, causing deviations in perceived eye color. Thus, eye color cannot reliably predict paternity.
