To understand the evolutionary relationship between genes and populations, phylogenetic analysis acts as a primary tool. It is a powerful approach to finding the evolutionary relationship between species and finding the similarities or differences among them. This also helps us understand biological diversity and genetic distance. For this, Dispan comes as the most efficient software which you can use for phylogenetic analysis and genetic diversity.

It is specifically designed to compute the average heterozygosity for each population. Knowing the heterozygosity values, we can find the average proportion of heterozygous individuals for a given trait. Besides, this software also helps in finding the standard error or simply variation for each population. You can also find the average gene diversity or total diversity within species and its associated parameters. Using these calculations, the DA distance between two populations can also be determined.


  • A simple yet useful tool to find the genetic distance between populations or determine the phylogenetic analysis.
  • It uses different methods, such as the neighbor-joining (NJ) method and the unweighted pair group method with arithmetic mean to find the DA distance between populations.
  • You can construct phylogenetic trees and sequence data from multiple samples.
  • It finds the Average heterozygosity and its standard error for each population.
  • The bootstrap test is used to construct dendrograms or phylogenetic trees so you can evaluate results using these trees.
  • It works on all kinds of devices and has no complex system requirements, so anyone with a computer can access its functionalities.

Dispan is highly useful when it comes to determining the phylogenetic structures of two species or populations. It provides accurate estimates of relatedness and offers a large variety of phylogenetic functions. You can use the maximum likelihood or distance matrix methods to calculate the reliability of trees/branches using bootstrapping or error resampling. This software takes very little storage space and has only 147KB file size. It is specifically built for Windows, but you can run it on any device.

Dispan uses different methods, such as neighbor-joining (NJ) and the unweighted pair group method, to construct phylogenetic trees or dendrograms.
