what are the two most common uses of dna fingerprinting
DNA profiling DNA profiling is most commonly used as a forensic technique in criminal investigations to identify an unidentified person or whose identity needs to be confirmed,[2] or to place a person at a crime scene or to eliminate a person from consideration. DNA profiling has also been used to help clarify paternity, in immigration disputes,[3] in parentage testing and in genealogical research or medical research. DNA fingerprinting has also been used in the study of animal and floral populations and in the fields of zoology, botany, and agriculture.[4]
Fingerprint powder Modern fingerprint powders have a variety of compositions, and are often a matter of personal choice by the expert using them or down to the standard procedure of the department or agency. Many agencies use proprietary powders produced by independent companies, and so the exact formulation of these powders is not revealed.
