Webbspecies, with one individual per species (27 ingroup taxa). To investigate the intraspeciﬁc variability, we analysed a second data set of only mitochondrial sequences that includes 64 ingroup individuals. The sequences of some of the taxa included in the mitochondrial data set were retrieved from GenBank. DNA isolation and sequencing WebbFor all loci, the average sequence divergence values for ingroup—outgroup pairs of taxa were higher than the divergences among the ingroup genera, which, in turn, were higher than the divergences within the ingroup genera. The levels of average pairwise sequence divergence among congeneric exemplars differed among pterioidean genera (Table 1).

In total, 107 samples of ingroup taxa were sequenced for 16S (444 bp) and 104 samples for COI (654 bp). This group was then subsampled to representatives of the recovered lineages, but due to problems with PCR amplification and/or gene sequencing, some samples failed to properly amplify for certain genes. rotate usb flash drive made in china

WebbConsiderable confusion remains among theoreticians and practicioners of phylogenetic science on the use of outgroup taxa. Here, we show that, despite claims to the contrary, details of the optimal ingroup topology can be changed by switching outgroup taxa.

The chosen outgroup is hypothesized to be less closely related to the ingroup than the ingroup is related to itself. The evolutionary conclusion from these relationships is that the outgroup species has a common ancestor with the ingroup that is older than the common ancestor of the ingroup. Choice of outgroup can change the topology of a phylogeny. Therefore, phylogeneticists typically use more than one outgroup in cladistic analysis. The use of multiple outgroups is preferable be… Webb21 okt. 2024 · Outgroup and ingroup are two groups defined in cladistics. The ingroup is the group of taxa that is investigated for determining …
