The Power Of The Gene: The Most Curious Genetic Mutation

Science says that the mutation is stable when the DNA code error creeps in and the light appears a living thing a little not the same as it was originally intended.Question only in what will be subjected to changes.Don't have a third hand, for example, among some ethnic groups there is a stable genotype for black hair and then suddenly red child is born – the mutation! Alas, or fortunately, the most beautiful mutations for some reason very poorly fixed and therefore are very rare.

In translation from scientific – the second row of eyelashes which should not be there. Such mutation meets also people, and at animals, and causes the second problems because filaments can stick into an eye. And human anatomy only on advantage – look at a speaking glance of Elizabeth Taylor, the bearer of this mutation, and you will understand everything.

Heterochromia

It when because of failures in hormonal cocktail the iris of the eye of eyes receives different quantity of a pigment because of what one eye becomes dark, brown, and the second remains light – green or blue.Looks unusually and it is even attractive, but only in case heterochromia congenital, because of a mutation.And here if the organism was already created and suddenly eyes began to change color, it is a big trouble, sign of a number of the most dangerous diseases.

Bright red hair

Ancient not for nothing thought out any sayings about red, now we know that all of them are mutants! Specifically in the 16th chromosome of a gene of MC1R there are two recessive alleles, as changes hair color for the "wrong" red. Though actually changes much deeper and include the shortage of melanin.

Freckles

The same failure in a gene of MC1R is responsible for emergence of freckles, but the phenomenon these extremely rare, 1-2% of all population of the planet.The ancient sign that freckles "burn" sunshine, is partly right.It's all about the same pigment melanin, which is responsible for the color of the skin and hair, but its concentration depends on the irradiation of the body with solar radiation.Respectively, when kids begin to run on the sun, to a freckle are shown very actively.

Green eyes, blue eyes

About 10,000 years ago there was a major and serious mutation in the DNA of our ancestors-the failure gave the gene HERC2.It is believed that he appeared in an ancient man who left a very extensive offspring, and therefore now the mutation is quite common, blue eyes have 40% of the European race.And here its version, a mutation with green eyes, meets at only 2% of people.Both there, and there it is all about melanin as a part of an iris of the eye therefore the most rare and at the same time tremendous combination: the red-haired green-eyed beauty with freckles.A well-known image of a witch, a girl not of this world, is not it?

Why at some people hair are painted evenly, and others locks are allocated? The reason in numerous mutations in genes of hair, failures which cause pigmentation violations. And it not only is beautiful, but also it is dangerous – what provoked failures, could leave also other marks and effects.
