what is genetic marker
A genetic marker is defined as a specific gene or DNA sequence that produces a detectable trait with a known location on a chromosome and that can be used to study family and population, identification of cells, species or individual. Introduction:
For each genetic locus, each person has two genetic markers, or alleles (alternate forms of the DNA sequence): one allele is inherited from their biological mother and one allele is inherited from their biological father.NA (DeoxyriboNucleic Acid) is the genetic material found in the cells of your body. A person receives half of their genetic material from their biological mother and the other half from their biological father.
