How does DNA profiling detect genetic differences between individuals?

Question

Quizplus · Accepted Answer

DNA profiling uses short tandem repeats (STRs) and other variable parts of the genome to detect genetic differences between individuals. STRs are regions of DNA that contain repeating units, and the number of repeats can vary between individuals. By analyzing the number of repeats at several different loci, scientists can create a unique genetic profile for each individual. Other variable parts of the genome, such as single nucleotide polymorphisms (SNPs), can also be used in DNA profiling. By comparing the genetic profiles of different individuals, scientists can determine whether they are related or unrelated.
