Does Face DNA Testing and the comparison of human hereditary characteristics really work?

Absolutely! We can start with the DNA hereditary trait of the human eye. Ultimately eye color is determined by your ancestral lineage, namely your immediate nucleus. Statistically the paternal side or the father’s side is the dominant source of DNA. This is especially true when comparing two males. Males are the only human species that carry the Y chromosome.

* Genetic determination. Eye color is an inherited trait influenced by more than one gene. These genes are sought using associations to small changes in the genes themselves and in neighboring genes. … A specific mutation within the HERC2 gene, a gene that regulates OCA2 expression, is partly responsible for blue eyes.

** A particular region on chromosome 15 plays a major role in eye color. Within this region, there are two genes located very close together: OCA2and HERC2. The protein produced from the OCA2gene, known as the P protein, is involved in the maturation of melanosomes, which are cellular structures that produce and store melanin. The P protein therefore plays a crucial role in the amount and quality of melanin that is present in the iris. Several common variations (polymorphisms) in the OCA2 gene reduce the amount of functional P protein that is produced. Less P protein means that less melanin is present in the iris, leading to blue eyes instead of brown in people with a polymorphism in this gene.

In layman’s terms this means eye color is genetically inherited. Hence the word you continue to hear, hereditary characteristics. We have an awesome eye color chart that will assist in determining what your eye color should naturally be based on the color of your parents eyes, namely your father’s.

This type of science and numerous other studies help us determine DNA Face Matching with considerable accuracy

At Face IT Technology, we investigate human genetic factors manifesting as face features through sophisticated DNA testing and evaluation. Eye colour is among the most diverse human features that may be identified by contemporary genetic studies. Therefore, how effective is our method for DNA testing of eye colour? Let’s examine some fundamentals regarding this characteristic:

What is the most common eye colour?

According to the eye color chart, the most common eye colour is brown; approximately 55% of people on the planet have brown eyes. Blue eyes are the second most prevalent hue on the planet after brown, accounting for around 17% of all eyes. A smaller percentage of individuals have amber, green, or hazel eye color.

How is eye colour determined chart?

Eye colour is influenced by a number of genes, particularly the ratio of brown to lighter pigments generated in the iris. From dark brown to bright blue and green, this mixture of pigments and variation in genes is what gives rise to an entire range of eye colours.

What is the coloured part of the eye called?

The retina, or iris, is the colourful portion of the eye. It has pigment cells, which use different concentrations of a pigment known as melanin to determine eye colour.

What percentage of people have green eyes?

Green eyes are found in just 2% of the globe’s population. Northern and Central Europeans are the ones who have them the most. Hazel eyes that have a green and brown tone to them are found in around 5% of the population.

Therefore, while eye color charts and percentages vary predictably around the world, knowing a person’s exact DNA profile gives more individualized information. This genetic finding is incorporated into the FaceIT DNA Technology tests to explain the appearance of features like skin, hair, and eye color. Overall, the results of our facial DNA tests demonstrate that using genetic markers to analyze human hereditary characteristics can produce accurate, practical results with a wide range of worthwhile uses.

Conclusion

With just a face DNA test, our sophisticated eye color DNA test can accurately determine a person’s precise eye color by analyzing for the major gene variations associated with eye color. Modern DNA testing may accurately uncover genetic markers for eye color and other face traits, giving us a better understanding of human origins and appearance.
