He
says in the Holy Qur'an: Have We his eyes * and tongue and lips [From: 8 -
10]Are
obvious to any creature the gift of sight and vision ... and God created the
Public many creativity creation of forms, colors and forms ..And
we'll talk about the subject of eyes and different colors and different
scientific reasons ...
* Genetics and eye
color:
Eye
color is the subject of much surprised researchers for centuries .. Even
science has provided us with a better understanding of the color of the
eyes,And how it is inherited.When
it comes in predicting eye color of the child, for example, one can almost be
sure that the child will be bornWith blue eyes. Children
newborns are often with eyes Zarkao slightly darker with increased
exposureTo
the sun from the age of three years and usually settle in permanent communities,
has changed color to becomeGreen,
Hazel, dark brown, gray and black
The
issue of eye color, and how transmitted from parents to offspring, has been a
subject of debate among geneticists for decades.And
thought for a long time that the eye color followed simple Mendelian inheritance
pattern.
Overall,
through the rules of Mendelian inheritance, eye color is inherited in a very
similar way to the way that inherit hair color:Genes
for dark colors are dominant - and this means that the qualities (or phenomena)
as a symbol of the primacy of the attributesEncoding
genes for color lighter.

Gaining
eyes substance called (melanin) produced by the body as a kind of dyes to the
skin and hair and thisColors vary from one
person to another.Every
part of the melanin has a dark brown color, if met these molecules heavily
became dark brown eye color.And
if you are afraid of density was brown in color, opening the same way gaining
the eyes of some people the color blue.Because
very light Malaninha material, and therefore reflect the color blue, which
derives from the reflectionSunlight
on the air with its blue sky and water and dust particles stuck in the
air.Thus
molecules absorb light eye melanin different colors in the
light,The show blue

Scientifically eye colors are divided into two sections:
1) eyes a
colored eyes: green, horny and infrastructure2)
The eyes of others are colored blue eyes
Merely
cause disagreement eye colors to two reasons: synthetic hand and
genetically
The
first reason; compositional terms, individuals with blue eyesContain
iris have only two layers, while individuals with colored eyes iris contains two
layersIn
addition to the third layer earn color eye color is blue, and note the gradient
and the difference in color colorfulDue
to differences in the density and thickness of the foam in between the layers of
the iris so we find in eye color gradient.
In
genetic terms, we find that the colored eyes model genetic AA or Aa as the
dominant attribute is the eyesInc.
A colorful and if met dominant gene with another recessive produces individual
colored eyes, and the individuals with blue eyesPossessing
genetically models is aa meeting must Mtnhieddin genes for the emergence of the
blue color of the eye.

Some interesting scientific facts about eye color:
Perhaps
you are aware that brown is the most common eye color in all parts of the world,
but did you know that the colorGreen largely is considered the
rarest? In
fact, less than 2 percent of the world's population has green
eyes.But
as one considers Turkey has the highest percentage of citizens who have green
eyes by 20 percent.There
are a number of countries - generally located in Asia and South America, and the
Middle East - where green eyes are almostBe completely
absent in the population.
Did
you know that blue eyes are the most common eye color of the Caucasian
population, more than black, and Venetian,And gray, and green .. In
fact, more than 80 percent of the population of Iceland color of their eyes
either blue or green eyes.There
are people who has appointed a blue and green, and some of them also there has
in some eye drops or dark Alhlat .. is a different symbolic
qualitiesWe
refer to the important information is that there is no pure color black eyes ..
& this requires the existence of Alsabgp matter by complete
..This
is impossible .. but you may see the color of dark brown eyes tend to black ..
but it's not black!
And
some of the people; especially in light of these developments are using contact
lenses .. to correct considering dispensingGlasses and to impart
color
In
conclusion not only say Hallelujah and praise Sobhan Allah Almighty created man
in the best stature .. God Hassan created also improved created ...
Amen
