This genome-scale estimate of relationships among species agrees with some prior estimates based on smaller molecular datasets [ 14, 15].
Because taxon sampling is limited in our study, adding more taxa might provide a better estimate of relationships and more insight about the true relationships among these taxa.
Our estimate of relationships among species of this group agree with previous studies, although the inclusion of S. condimenti in our trees is novel [ 6, 64].
However, given the congruence of the results among our various analyses, we feel our phylogeny is a reasonable estimate of relationships within the family.
The latter tree was poorly resolved and Pietsch and Orr [ 33] thus considered the former as the best estimate of relationships.
Arguably, the phylogeny presented here is therefore the best estimate of relationships in the ovenbird-woodcreeper assemblage to date, as it includes data from five independent loci and more taxa than previous studies.
Similar to the way both marker and pedigree information are used in matrix G LA, Goddard et al. [ 4] proposed a method to obtain an unbiased estimate of relationships for genomic prediction by regressing the IBS matrix onto the pedigree-based relationship matrix.
However, the limited number of available whole chloroplast genome sequences can result in misleading estimates of relationship [ 27, 30].
To what extend do tetra-nucleotides affect previous estimates of relationship between within-population heterozygosity and distance from sub-Saharan Africa?
It could be that a higher marker density reduces errors in the estimates of relationship between distant relatives, which may improve the contribution of ancient relationships to the accuracy of GW-EBV.
