This book is the output of Anthropological Survey of India's
National Project "DNA Polymorphism of Contemporary Indian
Population" conducted during 2000 to 2018. The book compiles the
independent and collaborative work of 49 scientific personnel.
Genomics facilitate the study of genetic constitution and diversity
at individual and population levels. Genomic diversity explains
susceptibility, predisposition and prolongation of diseases;
personalized medicine and longevity; prehistoric demographic
events, such as population bottleneck, expansion, admixture and
natural selection. This book highlights the heterogeneous,
genetically diverse population of India. It shows how the central
geographic location of India, played a crucial role in historic and
pre-historic human migrations, and in peopling different continents
of the world. The book describes the massive task undertaken by
AnSI to unearth genomic diversity of India populations, with the
use of Uni-parental DNA markers mtDNA (mitochondrial DNA) and Y
-chromosome in 75 communities. The book talks about the 61 maternal
and 35 paternal lineages identified through these studies. It
brings forth interesting, hitherto unknown findings such as shared
mutations between certain communities. This volume is a milestone
in scientific research to understand biological diversity of Indian
people at genomic level. It addresses the basic priority to
identify different genes underlying various inborn genetic defects
and diseases specific to Indian populations. This would be highly
interesting to population geneticists, historians, as well as
anthropologists.

The National Institute of Justice (NIJ) is the research,
development and evaluation agency of the US Department of Justice.
The NIJ is dedicated to improving knowledge and understanding of
crime and justice issues through science. NIJ provides objective
and independent knowledge and tools to reduce crime and promote
justice, particularly at the state and local levels. Each year, the
NIJ publishes and sponsors dozens of research and study documents
detailing results, analyses and statistics that help to further the
organization's mission. These documents relate to topics like
biometrics, corrections technology, gun violence, digital
forensics, human trafficking, electronic crime, terrorism, tribal
justice and more. This document is one of these publications.
In recent years, technological progress in DNA (deoxyribonucleic
acid) testing has made DNA evidence a predominant forensic
technique for identifying criminals when biological tissues are
left at a crime scene. DNA testing on samples such as saliva, skin,
blood, hair, or semen not only helps to convict, but also serves to
exonerate. The sophisticated technology makes it possible to obtain
conclusive results in cases in which previous testing had been
inconclusive. Postconviction testing will be requested not only in
cases in which DNA testing was never done, but also in cases in
which the more refined technology may result in an indisputable
answer. It is hoped this report, Postconviction DNA Testing:
Recommendations for Handling Requests, will help participants
through the postconviction process. The report is the work of the
Working Group on Postconviction Issues, one of five working groups
that report to the National Commission on the Future of DNA
Evidence. The suggestions are based on the group's consensus on how
defense counsel, prosecutors, judicial officers, victims'
advocates, and DNA laboratories can respond effectively at the
various stages of a postconviction request for DNA testing.
Cooperation on the part of law enforcement officials may be
crucial; materials needed for testing or retesting may be in their
possession. To properly implement the recommendations contained in
this report, participants in postconviction DNA proceedings need to
consider the category of the case in which the DNA testing is
sought and whether participants need to adjust the roles they
customarily play in adversarial proceedings.
The principal assignment given to the Research and Development
Working Group was to identify the technical advances in the
forthcoming decade and to assess the expected impact of these on
forensic DNA (deoxyribonucleic acid) analysis. Progress in forensic
analysis was slow until recently, but since 1985 more powerful
techniques have increased explosively. The first useful marker
system, the ABO blood groups, was discovered in 1900. The second,
the MN groups, came a quarter century later. By the 1960s, there
were 17 blood group systems known, but not all were useful for
forensics, and in the 1970s a few serum proteins and enzymes were
added. By the 1980s, some 100 protein polymorphisms were known but
most were not generally useful for forensics. The year 1985 brought
a major breakthrough. VNTRs (variable number of tandem repeats)
showed much greater variability among people than previous systems
and immediately began to be used for forensic studies. They are
still used, but are rapidly being replaced by STRs (short tandem
repeats). We can also expect improvements in collection and
purification techniques. Automation will make the process more
efficient and rapid, and we expect interpretative software for
analysis of complex problems, such as mixtures. There also is
progress toward miniaturization, using a combination of chip
technology and molecular genetics. Portable, handheld systems are
now working in laboratory experiments; how soon these will be
available for routine use is not clear. We also expect an
increasing amount of re-examination of cases in which the
conviction was based on evidence other than DNA. Greater automation
and higher throughput approaches will help reduce the backlog.
Formats that can analyze multiple STR loci in miniaturized, mobile
instruments are promised and should be available by this time. We
also expect improved sampling and storage techniques. Research in
the human genome and clinical research will produce many more
markers, some of which will be used to supplement the existing
procedures. We also expect integration of computers and internet
with analytical techniques to permit direct transmission of test
data between laboratories. There may be some transition to new
technologies, mainly to supplement the standard STRs. SNPs will be
widely used in medical and agricultural research, so there will be
many opportunities to carry these over for forensic purposes.
Within 10 years we expect portable, miniaturized instrumentation
that will provide analysis at the crime scene with computer-linked
remote analysis. Although this report looks to the future, we
emphasize that current state-of-the-art DNA typing is such that the
technology and statistical methods are accurate and reproducible.
STRs have proved to be very satisfactory for forensic use and are
being rapidly adopted by forensic laboratories. The difficulty and
expense of changing well-established and reliable procedures will
inhibit changes to other systems. For this reason, we believe that
STRs will be the predominant procedure during the next decade.
Methods of automation, increasing the speed and output and
reliability of STR methods, will continue. In particular we expect
that portable, miniature chips will make possible the analysis of
DNA directly at the crime scene. Techniques for handling minute
amounts of DNA or DNA that is badly degraded will become much
better. In particular, mitochondrial DNA will probably play an
increasing role in such difficult cases. Databases of DNA profiles
of convicted felons will be extensive and coordinated throughout
the States. International comparisons will be feasible and
increasingly common. In the future, it is likely that an increasing
number of suspects will be identified by database searches. The
statistical interpretation is difficult, particularly if future
databases include representatives of the population at large rather
than convicted felons.
DNA has proven to be a powerful tool in the fight against crime.
DNA evidence can identify suspects, convict the guilty, and
exonerate the innocent. Throughout the Nation, criminal justice
professionals are discovering that advancements in DNA technology
are breathing new life into old, cold, or unsolved criminal cases.
Evidence that was previously unsuitable for DNA testing because a
biological sample was too small or degraded may now yield a DNA
profile. Development of the Combined DNA Index System (CODIS) at
the State and national levels enables law enforcement to aid
investigations by effectively and efficiently identifying suspects
and linking serial crimes to each other. The National Commission on
the Future of DNA Evidence made clear, however, that we must
dedicate more resources to empower law enforcement to use this
technology quickly and effectively. Using DNA to Solve Cold Cases
is intended for use by law enforcement and other criminal justice
professionals who have the responsibility for reviewing and
investigating unsolved cases. This report will provide basic
information to assist agencies in the complex process of case
review with a specific emphasis on using DNA evidence to solve
previously unsolvable crimes. Although DNA is not the only forensic
tool that can be valuable to unsolved case investigations,
advancements in DNA technology and the success of DNA database
systems have inspired law enforcement agencies throughout the
country to reevaluate cold cases for DNA evidence. As law
enforcement professionals progress through investigations, however,
they should keep in mind the array of other technology
advancements, such as improved ballistics and fingerprint
databases, which may substantially advance a case beyond its
original level.
