Genetic Marker

A genetic marker is a specific sequence of DNA that can be used to identify a particular gene or genetic trait. These markers serve as landmarks on chromosomes and help scientists track inheritance patterns, study genetic diseases, and understand the genetic basis of traits. By analyzing these markers, researchers can determine relationships between individuals, identify variations in the DNA, and even link specific markers to certain conditions or qualities, such as susceptibility to diseases or responses to medications. Essentially, genetic markers act like signposts in our DNA, guiding researchers through the complex landscape of our genetics.
