This file is about:

• DNA testing, DNA typing, genetic fingerprinting
• Majority of DNA is the same for organisms in the same species but there are pieces, regions/patterns that differ within the species
• Knowing these DNA sequences is the basis of DNA profiling
• DNA sequencing; determining the nucleotide sequence of a given DNA fragment
• Knowing the sequence of DNA fragments can help the sweetpotato breeder/researcher to apply molecular markers in sweetpotato breeding to:
  • Cultivar identification
  • determination of ‘hybridity’
  • Assess genetic diversity
  • genetic mapping
  • gene tagging
  • gene flow
  • molecular evolution study
