an umbrella term for homeolog and ohnolog?
Unfortunately, there is no such term. Look at Glover et al. 2016 for a proposal how to unify the ploidy related homology terms, none of the words describes exactly what I searched for, so I at least compiled the relevant vocabulary

homoeolog/homeolog - homologous chromosomal sets in an organism diverged in isolated populations/subspecies and broght back by a hybridization event; note that the two spellings with exactly the same meaning are possible
ohnolog - homologous chromosomal sets originated from a whole-genome duplication (WGD) event; however usually this is used for ancient WGD events (like the R1 and R2 at the base of vertebrates, or the WGD at the base of bony fishes). It is not really possible to distinguish between WGD and hybridization in these ancient cases and therefome ohnologs perhaps suit &quot;unknown&quot; category better.
homologous chromosomes - chromosomes that pair during meiosis (does not strictly correspond to the homology in the context of molecular evolution)
homologous sequences/homologs - any sequences that have a common ancestor (as used in molecular evolution; but does not have to be on a genome-scale or within a genome; tandem duplicates or orthologs in two species are also homologous sequences)

2020 update:
I asked when I was writing this paper. I needed the term to describe the heterozygosity structure of some polyploids and I ended up calling them homolog (A &lt;-&gt; A' divergence) and homoeolog heterozygosity (AA' &lt;-&gt; BB' divergence) or composite when I was unable to set them apart (the majority of cases in fact).
