WebApr 18, 2024 · In most applications, F-statistics are estimated from data, and then used as tests of treeness.In particular, under the assumption of a tree, F 3 is restricted to be non-negative, and many F 4-statistics will be zero [40,42], and data that violates these constraints is incompatible with a tree-like relationship between populations.The canonical alternative … WebIn this paper, we show how the Analysis of Molecular Variance (AMOVA) framework can be extended to include autopolyploid data, which will allow calculating several genetic summary statistics for estimating the strength of genetic differentiation among autopolyploid populations (FST, φST, or RST.).

The concept of limit is given intuitively. The concept of differentiation, rate of change and problem of extremum are discussed.
WebThe genome scan method implemented in the package is a Fst approach. The function compares single-locus estimates of a population differentiation statistic with the genome-wide background. Then, it converts those estimates into statistical significance values after recalibration of the null-hypothesis (Martins et al. 2016, Francois et al. 2016).
