As exchanges between countries continue to deepen, the number of mixed-race children is increasing. Zhenghejun discovered a phenomenon that most mixed-race children born in black people with other skin colors inherit the skin color and appearance of black people. Why is this?
For this problem, after understanding it, it was found that the main reason is that the black dominant gene is too powerful. When the dominant gene is passed on to the next generation, it can often defeat a number of recessive genes and pass on its characteristics to the next generation. This dominant gene is the dominant gene that dominates the appearance of the next generation. The more common dominant genes include: big thumb cannot bend backward, dimples, high nose bridge, big eyes, double eyelids, long eyelashes, big ears, bald head, and dark skin.
For this reason, as long as one of the parents is black, their next generation will have a significant black appearance to a large extent, and the skin color of mixed-race children is often between their parents. For example, the familiar US President Obama is a mixed-race child. From the photos of him with his family when he was a child, he can see that his skin color is lighter than his father.
In addition, children of black people and other races actually have less than 10% chance of giving birth to white-skinned children. There are many examples in the basketball world:
NBA famous power forward Griffin
Warriors No. 2 star Klay Thompson
Rockets l1 Austin Rivers
NBA star NBA star Nowski One of the children born to
Although the probability of black children born to black people and other people with skin color has extremely high probability of dark skin, there are still exceptions. A black couple abroad once gave birth to a white-skinned blonde hair. Geneticists conducted research on this. Although the possibility of albinism was ruled out, the specific reason could not be found.
But in this case, even if the skin color changes, the black skin gene will still be inherited. It is possible that a child with black skin will appear in a certain generation in the future. If the descendants continue to mix blood in the inheritance, the probability will be continuously reduced. Generally speaking, the probability of white skin for black people with mixed blood must reach one quarter of the probability of more than two generations of people combining with white people. The specific probability depends on the pure course of the black bloodline. The specific probability depends on the bloodline of the black people. The Pushkin family is a family that gradually turns white from black skin. Pushkin's grandfather is a pure-bred black man. By constantly giving birth to mixed-race children with white people, the fifth generation of Pushkin's granddaughter can basically no longer see the shadow of black man, and the same goes for future descendants. Below is a photo of the descendants of the Pushkin family:
So, it is difficult to turn from black to white to yellow, but it only takes one time to get from white to black to black.
