DNA polymorphism refers to the occurrence of variations in the DNA sequence among individuals of the same species. These variations arise due to changes in one or more nucleotides in the DNA and are inherited from one generation to another. A DNA polymorphism is considered significant when the least common variant occurs in more than 1% of the population. Such variations do not necessarily cause disease; instead, they contribute to genetic diversity and provide valuable markers for studying inheritance, evolution, population history, and relationships among different human groups. In comparative ethnography, DNA polymorphism is an essential tool for understanding the biological affinities, migration patterns, and evolutionary relationships of populations. It enables anthropologists to compare genetic similarities and differences among ethnic groups and reconstruct _______ ________ __________ ___ _________ ______ ______.
