Welcome to the GenAlEx 6.5 website!


GenAlEx: Genetic Analysis in Excel is a popular cross platform package for population genetic analysis that runs within Microsoft Excel. GenAlEx offers analysis of codominant, haploid and binary genetic loci and DNA sequences. Both frequency-based (F-statistics, heterozygosity, HWE, population assignment, relatedness) and distance-based (AMOVA, PCoA, Mantel tests, multivariate spatial autocorrelation) analyses are provided. In GenAlEx 6.5 we introduce exciting new features including calculation of new estimators of population structure: G’ST, G’’ST, Jost’s Dest, and F’ST via AMOVA, Shannon Information analysis, linkage disequilibrium analysis for biallelic data, and heterogeneity tests for spatial autocorrelation analysis. Direct data export is provided to more than 30 other software packages, and indirectly via common formats to many more packages. New teaching tutorials and extra step-by-step options are also included. The comprehensive independently written guide has been fully revised.

GenAlEx 6.5 Overview

GenAlEx 6.5 (Peakall and Smouse 2006, 2012) offers a wide range of population genetic analysis options for the full spectrum of genetic markers within the Microsoft Excel environment on both PC and Macintosh computers. When combined with its user-friendly interface, rich graphical outputs for data exploration and publication, tools for data manipulation and export options to many other software packages, we believe that GenAlEx offers an ideal launching pad for population genetic analysis by students, teachers and researchers alike.
