body: <p>I read a recommendation of how to find non-duplicated chromosomes:
  <a href="https://stackoverflow.com/questions/10473397/using-jgap-genetic-algorithm-library-and-the-duplicated-chromosomes">using JGAp (genetic algorithm library) and the duplicated chromosomes</a></p>
  
  <p>How do you find a chromosome with non-repeated alleles using JGAP?</p>
