•  
• how forensic scientists take advantage of genomic
  variations in noncoding regions of DNA
• the techniques of polymerase chain reaction (PCR)
  and gel electrophoresis
• Introduction In recent years, law enforcement
  has been revolutionized by molecular biology.
  When human tissues are left behind at crime
  scenes, these tissues can be collected and
  processed to yield samples of DNA, which can then
  be treated to isolate specific DNA fragments that
  are highly variable in the human population.

• There is a fierce competition among individuals
  within any species, humans included, to gain
  access to reproductive privileges. The fittest
  a term that signifies the largest, prettiest,
  and most sexually attractive members, succeed in
  predominantly mating and having offspring, while
  the less attractive ones often do not. What is
  the role of such sexual selection from an
  evolutionary standpoint?
