The tests do not look at the accurate technology to determine paternity. It has information in the genes but instead examine come a long way from application in non-coding DNA that separated the genes along immigration case to identification of foetus of the chromosomes. Specifically the DNA is rape victims and missing persons/ deceased. examined where there are large numbers of DNA paternity testing in forensic casework is repeated sequences of letters along its length The greatly based on comparison with reference pattern of different numbers of STRs at certain biological samples of close blood relatives. The sites on the chromosomes are used to create a choice of reference samples depends largely on DNA pattern or DNA fingerprint. Short tandem the authenticity of biological relationship with repeat (STR) technology is used to evaluate the individual in question. However, in certain specific regions (loci) within nuclear DNA. conditions the relationship may not be Variability in STR regions can be used to biological. Today with the advent of new distinguish one DNA profile from another. DNA reproductive technologies like IVF, surrogacy profile for a multiplex of 15 autosomal STR etc, it becomes imperative to review the markers is generated and obligatory alleles are problems in forensic paternity testing for legal compared with parents/ siblings/ close relatives.
