Analysis of molecular variance AMOVA , is a statistical model for the molecular algorithm in a single species , typically biological. This program, which runs on Windows , is called Arlequin and is freely available on Excoffier's website. Another implementation is in Info-Gen , which also runs on Windows. The student version is free and fully functional. Native language of the application is Spanish but an English version is also available. An additional free statistical package, GenAlEx, [2] is geared toward teaching as well as research and allows for complex genetic analyses to be employed and compared within the commonly used Microsoft Excel interface.

Analysis of molecular variance is a nonparametric analog of traditional analysis of variance. This method is widely used in population genetics to test the hypothesis that genetic diversity within two populations is not significantly different from that which would result from pooling the two populations Excoffier et al. A P-value is calculated by measuring the fraction of randomizations of the rows and columns in a distance matrix where the observed SSW is less than or equal to the randomized SSW values. To run the tutorial below please download the files and follow along The phylip and design parameter are required. The phylip option allow you to enter your phylip formatted distance matrix. The design parameter allows you to assign your samples to groups when you are running amova. The design file is a simple tab-separated text file, with each line listing a sample ID corresponding to entries in the distance matrix and a group ID. The sets parameter allows you to specify which of the sets in your design file you would like to analyze. The set names are separated by dashes. The default is all sets in the designfile. Learn more!

This procedure was initially implemented for DNA haplotypes, but applies to any marker system. The implementation of AMOVA in poppr requires two very basic components: 1 A distance matrix derived from the data and 2 a separate table used to partition the data into different stratifications. The distance matrix can be calculated using any distance as long as it is euclidean. We can see that this data set contains clonal data and has three stratifications where the first is really a combination of the other levels. We can take a look at the different stratifications, populations or subpopulations:. In this example, we have a data set of individuals sampled from two fields located in Athena or Mt.

See adeamova ade4 and pegas::amova pegas for details on the specific implementation. See Details below. See clonecorrect for details. If this is set to NULL default , the raw pairwise distances will be calculated via dist. Options are adequasieuclid Default , adelingoes , and adecailliez. You can set the parameters with algorithm and threshold arguments.

Bioinformatics 28, — These provide more information because within sample individual variance is also assessed. In panmictic populations, we would expect to see most of the variance arise from within samples. Conclusions AMOVA is a powerful tool that can help support hypotheses of population structure due to clonal reproduction or isolation without making assumptions about Hardy-Weinberg equilibrium. Here we will show what the populations look like before and after shuffling:. In the case of clonal organisms, this would help support a hypothesis of clonal reproduction.

Autopolyploids present several challenges to researchers studying population genetics, since almost all population genetics theory, and the expectations derived from this theory, has been developed for haploids and diploids. Also many statistical tools for the analysis of genetic data, such as AMOVA and genome scans, are available only for haploids and diploids.
