Molecular markers

Molecular markers are specific sequences in DNA that serve as biological signposts, identifying genetic variations or traits within an organism’s genome. They are like genetic fingerprints used in research, medicine, and breeding to detect differences, map genes, or track inheritance. These markers can be found in various forms, such as single nucleotide polymorphisms (SNPs) or microsatellites, and help scientists understand genetic diversity, diagnose diseases, or select desirable traits in crops and animals efficiently. Essentially, molecular markers are tools that reveal genetic information precisely and reliably.
