The same might be applied to the ortholog/paralog definition Assuming a mean gene length in I. scapularis of 10,589 bp (See ) and 293-1443 paralog clusters (Vmatch low stringency GM and TC analysis, respectively), we estimate that duplicated genes and multi-gene families could account for at most ~ 0.3-1.4 % of the ~ 2.1 Gbp genome.

Orthologs and paralogs are two fundamentally different types of homologous genes that evolved, respectively, by vertical descent from a single ancestral gene and by duplication.

"By definition, orthologs are genes that are related by vertical descent from a common ancestor and encode proteins with the same function in different species. By contrast, paralogs are homologous genes that have evolved by duplication and code for protein with similar, but not identical functions."

These are derived from a common ancestor gene through vertical descent (i.e. passed down to new organisms during speciation events).

Paralog vs ortholog

2019-12-25 · The key difference between orthologous and paralogous genes is that orthologous genes are the homologous genes found in different species due to speciation, and they perform the same function. In contrast, paralogous genes are the genes found within a single species due to duplication and they can have different functions. Both orthologs and paralogs are types of homologs, that is, they denote genes that derive from the same ancestral sequence. Orthologs are corresponding genes in different lineages and are a result of speciation, whereas paralogs result from a gene duplication.

Having >= 80% residues in both sequences included in the BLASTP alignment, 3. Ortholog: Related by speciation event Super-ortholog: Two genes are each other's super-ortholog if every node on a path separating them in a gene tree corresponds to a speciation event Co-ortholog: Paralogs produced by duplications of orthologs subsequent to a given speciation event. Commonly observed between distantly related species.
