Genetic diversity across the plant families

The scatter plot displays the genetic diversity of all plant families according to two measures of sequence conservation:

- Percentage of identical sites (PIS)- The PIS is calculated by dividing the number of equal positions in the alignment for an oligonucleotide by its length.
- Percentage of pairwise identity (PPI)- The PPI is calculated by counting the average number of pairwise matches across the positions of the alignment where the oligonucleotide is located. We then divide this value by the total number of pairwise comparisons.
