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. Vernon over 8 or 10 different soil samples within each field. We want to see if most of the variance is observed at the sample, field, or regional level. In panmictic populations, we would expect to see most of the variance arise from within samples. If we see that the most of the variance occurs among samples within populations or among populations, then there is evidence that we have some sort of population structure. In the case of clonal organisms, this would help support a hypothesis of clonal reproduction. Since Aphanomyces eutieches is known to be clonal, we would not expect most of the variance to come from within samples. The degrees of freedom the Df column should match what we expect from our not clone-corrected data. We expect variations within samples to give the greatest amount of variation for populations that are not significantly differentiated.

The design file is a simple tab-separated text file, amova, with each line listing a sample ID amova to entries in the distance matrix and a group ID.

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.

Resources for conducting population genetic and phylogenetic analyses in the R computing environment are continually improving, and to date several packages have provided functions for estimating phi-statistics and hierarchical patterns of population variance partitioning using AMOVA analysis of molecular variance; Quattro et al. Hypostomus sp. Here, in my case, the data were produced by NGS sequencing on a ddRAD-seq genomic library that included outgroup samples, in order to facilitate downstream phylogenomic analyses. Including outgroup individuals would in fact bias the results. The purpose of showing these steps in this order is to demonstrate that we can easily convert from genind to genclone; however, it is better—in fact, necessary—that we do this for AMOVA while adding information about the hierarchical relationships population hierarchy of the dataset.

We expect variations within samples to give the greatest amount of variation for populations that are not significantly differentiated. These provide more information because within sample individual variance is also assessed. 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. Population genetic software for teaching and research-an update. The student version is free and fully functional. From this output, you can see three histograms representing the distribution of the randomized strata. 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. 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:. Another implementation is in Info-Gen , which also runs on Windows. This software allows for calculation of analyses such as AMOVA, as well as comparisons with other types of closely related statistics including F-statistics and Shannon's index, and more.
