Molecular markers used in forensic genetics.

Area of Science:

• Forensic Genetics
• Molecular Biology
• Genetics

Background:

• Forensic genetics has seen rapid advancements since the 1980s.
• Minisatellite sequences were early markers, now largely replaced by more sensitive methods.
• Current forensic science relies on advanced molecular techniques for DNA analysis.

Purpose of the Study:

• To review the evolution of techniques and molecular markers in forensic genetics.
• To highlight the transition from minisatellites to microsatellites and single nucleotide polymorphisms.
• To discuss emerging trends like phenotyping in forensic investigations.

Main Methods:

• Review of historical and modern molecular markers used in forensic genetics.
• Analysis of techniques for DNA profiling, including those for degraded samples.
• Exploration of single nucleotide polymorphisms for ethnicity and phenotypic trait determination.

Main Results:

• Minisatellite sequences have been superseded by microsatellite markers for genetic databases.
• Single nucleotide polymorphisms are crucial for analyzing degraded DNA and inferring traits.
• Forensic genetics now enables determination of ethnicity and physical characteristics.

Conclusions:

• The field of forensic genetics has progressed substantially in its methodologies and applications.
• Modern molecular markers offer enhanced sensitivity and broader applications, including phenotyping.
• Future trends point towards more sophisticated genetic analyses for comprehensive forensic identification.
