How can you use “presence-absence” in a sentence? Here are some example sentences to help you improve your vocabulary:

Here, we compare the topologies produced with five, largely independent approaches to genome-tree building: i) presence-absence of genomes in Clusters of Orthologous Groups of proteins (COGs); ii) conservation of local gene order (pairs of adjacent genes) among prokaryotic genomes; iii) distribution of percent identity between apparent orthologs; iv) sequence conservation in concatenated alignments of ribosomal proteins; v) comparative analysis of multiple trees reconstructed for representative protein families.
A quantitative comparison of the tree topologies using the symmetric distance method showed that the presence-absence tree was most different from the trees made by the other methods (Table 2).
volcanium ), a 0/1 matrix analogous to the one used for the presence-absence of individual genes was constructed, and a tree was built using Dollo parsimony [ 38 ] . A parsimony method was chosen for this analysis because the presence-absence of a conserved gene pair in a genome can be naturally treated in terms of character states.
Parsimony trees based on the presence-absence of conserved gene pairs in prokaryotic genomes
The topology of the tree based on gene pair conservation seems to carry a stronger phylogenetic signal than the gene presence-absence tree because it correctly groups together related free-living and parasitic bacteria despite major differences in gene repertoires (Fig.
