Parsimony-informative sites : Polymorphic sites with a minimum
of two alleles that are each present at least twice in the population.
Non-informative sites: Polymorphic sites that are unique in the
population (singleton sites).
Haplotype diversity: The probability that two given sequences
from two different haplotypes belong to two different regions or
populations.
Nucleotide diversity : The average number of nucleotide
substitutions per site between two sequences (Lynch and Crease 1990).
Average number of nucleotide differences : The average number of
nucleotide differences (either Indels or SNPs) within a given
population.
Indel events : The number of insertions/deletions in the genomic
region.
A + T (%) : A+T content in the genomic region.
