Area of Science:

  • Bioinformatics
  • Population Genetics
  • Computational Biology

Background:

  • Molecular profiles, or DNA fingerprints, are crucial for assigning individuals to known population groups.
  • Identifying informative genetic markers can significantly reduce the time and cost associated with profile analysis.

Purpose of the Study:

  • To develop and propose a genetic algorithm (GA) for identifying promising candidate markers from molecular profiles.
  • To enable efficient screening of markers for subsequent experiments.

Main Methods:

  • A genetic algorithm (GA) was employed to analyze molecular profile data.
  • Simulated datasets were used to determine optimal GA parameters and validate its performance.
  • The GA was designed to identify profile components (markers) associated with specific population groups.

Main Results:

  • The proposed GA successfully identifies informative genetic markers from molecular profiles.
  • Analysis of simulated data confirmed the GA's ability to find markers associated with considered groups.
  • Reasonable parameter values for the GA were established through simulation.

Conclusions:

  • The developed genetic algorithm offers an effective approach for screening candidate genetic markers.
  • This method can optimize resource allocation in population genetics studies by pre-selecting relevant markers.
