What is AMOVA test used for?

AMOVA stands for Analysis of MOlecular VAriance and is a method to detect population differentiation utilizing molecular markers (Excoffier, Smouse & Quattro, 1992). This procedure was initially implemented for DNA haplotypes, but applies to any marker system.

How do I run Arlequin software?

Installation

  1. Download Arlequin35. zip to any temporary directory.
  2. Extract all files contained in Arlequin35. zip in the directory of your choice.
  3. Start Arlequin by double-clicking on the file WinArl35.exe, which is the main executable file.

How is AMOVA calculated?

The ρ-statistic can be calculated in an AMOVA by first calculating a matrix of squared Euclidean distances for all pairs of individuals, based on the within-individual allele frequencies.

What does pairwise FST mean?

Abstract. Populations are shaped by their history. It is crucial to interpret population structure in an evolutionary context. Pairwise FST measures population structure, whereas population-specific FST measures deviation from the ancestral population.

What is Arlequin used for?

Arlequin provides methods to analyse patterns of genetic diversity within and between population samples.

How do I make an Arlequin file?

Now Go File, save/export data as, choose arlequin data format. It will ask you for a haplotype data file name to save, choose the name of your datafile and hit save, it will then ask you for an arlequin project file name, choose the same name (the file extension will be different), hit save.

What is molecular variation?

You are probably familiar with the idea that you have a variation of genetic makeups in a population. But even within an organism you have variation in the types of molecules that an organism can produce and when they produce them.

Why are haplotypes useful?

Haplotype maps of different populations To the extent that populations differ in their haplotype structure, it may be useful to study different populations during different stages of the process of finding disease genes.

How do you interpret FST values?

Genetic Differentiation of Populations Fst is a measure of population differentiation due to genetic structure. An Fst value greater than 0.15 can be considered as significant in differentiating populations (Frankham et al., 2002). Thus, a significant divergence was found within each of the C.
