Proportion of relationship coefficient within a confidence interval of ${\widehat{r}}_{obs}\pm 0.05$ assuming autotetraploid genotypes with different numbers of loci and alleles based on simulations with uniform distribution of ancestral alleles for each relationship. Methods: VR (extended Van Raden), PD (pseudo-diploid), FA (full-autopolyploid) MM (method-of-moments), ML (maximum-likelihood), RI (extended Ritland), LO (extended Loiselle), and WE (extended Weir). Biallelic methods (VR, PD, and FA) were just used for two alleles. *Biallelic methods (VR, PD, and FA) considered only two alleles scenarios, plotted line extended to better comparison.
