Ethnic traits refer to the characteristics and features that are commonly associated with specific ethnic groups. These traits can include physical attributes, such as skin color, hair type, and facial features, as well as cultural aspects like language, traditions, and customs. Ethnic traits help to define the identity of a group and can influence how individuals within that group relate to one another and to others. These traits are often shaped by a combination of genetics and environmental factors. For example, the geography of a region can affect the lifestyle and practices of its inhabitants, leading to distinct cultural expressions. Understanding ethnic traits is important for appreciating the diversity and richness of human societies.
