How do you define a homolog, ortholog, or paralog? Family, superfamily,
subfamily, cognate, counterpart, related, homologous, --Do you use other
words for describing relationships among homologous genes? And, how would
you use these words? Is there good references for how we can accurately
distinguish these words? I know there is no simple answer for this. But,
I would like to know how molecular evolutionalists are using these words.
Thanks in advance.
