主要是遗传多样性和杂交优势的影响。
Some people perceive mixed-race individuals as more attractive, and there are several reasons proposed for this perception.
Biological explanations:
- Genetic Diversity: Offspring of parents from different ethnic backgrounds inherit a broader range of genes. This genetic diversity can contribute to traits commonly associated with beauty, such as facial symmetry, smoother skin, and healthier hair. Studies suggest a link between facial symmetry and attractiveness.
- Hybrid Vigor (Heterosis): Crossbreeding in genetics can lead to "hybrid vigor," meaning offspring may exhibit increased genetic fitness and health. This could result in physical advantages like clearer skin and more youthful appearances, which can contribute to attractiveness.
