Can anybody please clarify the difference between paralogous vs orthologous genes. I am having a hard time differentiating and understanding them

Hi

I personally didn't come across these terms while I was studying or on my test but wiki has a pretty good explanation.

Hope this helps.

Orthologs = gene homologies found between other species. I just remember "O" for "Other species"

Paralogs = gene homologies found within the same species. These can arise via duplications or transposons.
