A genetic marker is a gene whose location on a chromosome is known and can be used to identify a species. Genetic markers are divided into two groups, biochemical markers that can detect variations in proteins and amino acids, and molecular markers that detect DNA variations. Some of the most commonly used genetic markers are:
- RFLP (or Restriction fragment length polymorphism) – a technique using restriction enzymes to cut DNA strands at different lengths
- SSLP (or Simple sequence length polymorphism) – difference in DNA sequences between individuals. The varying lengths are often used to understand variations between two members of the same species
- AFLP (or Amplified fragment length polymorphism) -a technique using restriction enzymes to digest DNA fragments that than creates a unique DNA fingerprint than can be compared
- RAPD (or Random amplification of polymorphic DNA) – randomly amplifies segments of DNA creating a semi-unique profile
- VNTR (or Variable number tandem repeat) – a specific genome location where a sequence of nucleotides is organized as a tandem repeat
