How do ALU sequences contribute to the genetic diversity in the human population?

Allele-specific long-range PCR (ALU) sequences contribute to genetic diversity in the human population by serving as markers for genetic variation. These sequences are repetitive elements in the human genome that can undergo mutations, leading to different alleles or versions of the sequence. By studying these variations in ALU sequences, researchers can track genetic diversity and understand population dynamics, evolutionary history, and disease susceptibility.
