The terms ortholog and paralog have wide acceptance. Yet, we find that they are used in nuanced ways by different people. Sure enough, here is some of what the Internet comes up with:
- ortholog: a gene from a disparate species, so similar in genetic sequence that it is assumed to have originated from a single gene in a common ancestral species.
- ortholog: either of two or more homologous gene sequences found in different species.
- orthologous: exhibiting orthology; having been separated by a speciation event.
- orthologs: homologous genes that result from speciation events (as opposed to paralogs, which result from duplication and subsequent divergence in a lineage).
- orthologous: groups of genes or proteins from different organisms that have the same function are said to be orthologous.
- orthologous: genes in different species are orthologous when their phylogeny is identical to the phylogeny of the species.
We deleted the ones that seemed like duplications (paralogs?). We find the first one most to our liking. Which do you think is most useful?
lol. Way to point out one of the hardest parts of graduate school. While learning NEW information....where do you get it?!?!? when do you trust it?!?!? how do you know that you are getting the best answer?!?!?!
...what a conundrum.
