Everyone's appearance is determined by many genes, and parents' appearance characteristics may not be directly passed on to their children. The combination of genes is very complicated and random, and sometimes there will be some unexpected results. In addition, appearance is also influenced by environmental factors, such as diet and living habits.

However, appearance is not the only criterion to measure a person's value. Everyone has his own unique charm and advantages, and inner quality and personality are often more important than external beauty.
