Molecular makers are particular pieces of DNA that can be distinguished inside the entire genome. Molecular markers are the general assays that permit location of the arrangement contrasts between two or more person. Sub-atomic markers are found at particular areas of the genome. They are utilized to "banner" the position of a specific quality or the legacy of a specific trademark or sought attributes Definition A sub-atomic marker is a DNA arrangement that is promptly identified and whose legacy can undoubtedly be observed. This is utilized to stamp an attribute in living creature MORPHOLOGICAL MARKER : Classical markers MOLECULAR MARKERS : Variation in full scale particles BIOCHEMICAL MARKERS GENETIC MARKERS ISOENZYME PROTEIN RFLP AFLP RAPD They are protein delivered by declaration of quality endless supply of DNA Low polymorphism Requires articulation of characteristic/ quality Dominance impact Expression sex constrained Expressed late in life.
