What are the colors of hair and eyes of people from different countries? Thank you.

People in different countries have different hair and eye colors. The color of human hair and eyes is determined by genes, and genes are influenced by the environment and geographical location of human ancestors. The following are the general characteristics of each race:

1. yellow people: usually yellow skin color, black and straight hair, and black or brown eyes.

2. White race: Generally, the skin color is light, the hair is soft and wavy, the eyes are green, grayish brown, blue or black, and the hair is golden or brown.

3. Black race: usually the skin color is black or dark brown, the hair is black, short and curly, and the eyes are black.

However, these are general characteristics and do not mean that all people are completely consistent. Human genetic variation is universal, so people may show different characteristics in some aspects. In addition, anthropologists also pointed out that the differences in human biodiversity are not only skin color and hair, but also facial features, genetic diseases and many other aspects. Therefore, answering this question requires more detailed classification and research.
