Why Human Skin Color Is Different?
The color of human skin in each region is different. There are black, white, yellow, and so on. For example, people in Africa have dark skin whereas people in Europe tend to have white or pale skin. While in the Asian region the population tends to be white rather yellow. What caused it?
Basically human skin color is influenced by various chemical compounds such as melanin. These chemical compounds react to the color of human skin. Melanin also reacts to the weather of the human dwelling area. For example, why are black Africans? This is due to the weather in the area.
When the skin is exposed to sunlight then melanin will change the skin color to dark to protect the skin. While in areas less exposed to sunlight the skin will be brighter to give more pro vitamin D. No wonder not if in areas such as Africa, the population is dark.
That character is then passed on by the parents. Genetic factors in this case are also very influential. For example, two dark-skinned parents can be ascertained that their children will also be dark skinned. Likewise with parents who are light skinny then their children tend to be bright.
But there are also people who suffer from albinism or often called albino. For some people tend to have no body pigment so it will get white skin despite his dark-skinned parents. Albinism is one of the abnormalities caused by the lack of substance melanin pigment or dye in the body. Generally people experiencing albinism will be very sensitive and not resistant to sun rays.
What about cross-breeding?
In recent years cross-race marriages have grown in popularity. White marriage and blacks were also more prevalent. This causes the skin color of the offspring varies. There are black and white.
THE FORMULA OF CROSS-BREEDING
In Science, cross-breeding is a marriage done by two genetically distinct individuals in one species. In the world of agriculture or animal husbandry the purpose of interbreeding is to obtain new varieties in the species and is the most superior when compared with others. But cross-breeding can also occur between races. For example white skin with black skin.
This cross-breeding can bring diverse offspring. It can be black or white. The possibility has the same value that is 50 percent. It's just that in this case the dominant nature of skin color is also decisive. For example black color is more dominant then the child will tend to be black.
So basically the skin color is just a color. There can be no conflict just because of the color of the skin.
