  1. 1# Number of samples correspond to number of plants from which leaf tissue was assayed.
  2. 2Percent (%) of missing data is the percentage of markers that did not return data computed per cycle.
  3. 3Percent of polymorphic loci is the percentage of polymorphic loci to the total number of loci (polymorphic and monomorphic) per cycle.
  4. 4Number of effective alleles are the number of alleles that can be present in the population.
  5. 5Observed heterozygosity is the number of markers within a population that are heterozygous calculated per cycle based.
  6. 6Expected heterozygosity is the probability that at a single locus, any two alleles chosen at random from the population are different to each other.
  7. 7Fixation index is the measure of reduction in heterozygosity.
