POPTREE

POPTREE constructs population trees and quantifies genetic diversity and differentiation from allele frequency data to analyze evolutionary relationships among populations.

Key Features:

• Population tree construction: Computes distance measures from allele frequency data to construct population trees representing evolutionary relationships.
• Average heterozygosity (H): Calculates average heterozygosity (H) as a measure of within-population genetic diversity.
• Genetic differentiation metrics: Computes G(ST), standardized G(ST), and Jost's D to assess genetic differentiation among subdivided populations.
• Data compatibility: Accepts genotype data in GENEPOP format.

Scientific Applications:

• Evolutionary analysis: Infers evolutionary relationships among populations using population trees derived from allele frequency data.
• Population genetics: Assesses within-population diversity and between-population differentiation using H, G(ST), standardized G(ST), and Jost's D.
• Comparative and temporal studies: Investigates patterns of genetic diversity and differentiation across different species or within a single species over time, including datasets with high variability.

Methodology:

Analyzes allele frequency data and calculates distance measures to construct population trees, integrating average heterozygosity (H), G(ST), standardized G(ST), and Jost's D.
