Is there a word that refer to homologous chromosomes within a polyploid species? If I have AABB species, what is A to B?

The words "homeolog" and "ohnolog" are reserved for the cases if the homologous chromosomes have diverged via speciation or whole genome duplication event. But what if we just don't know?

I hesitate to use word "homologous chromosomes" since they do not for a choromosome pair anymore, they are homologous in sense of an recent common chromosome ancestor.

    $\begingroup$ I think homolog is as good a term as you'll get, though I'm certainly not an expert in this area. $\endgroup$ – canadianer Oct 24 '18 at 23:22
  • $\begingroup$ In the case of (A+A'+B+B'), A and A' are homologous chromosomes. In canonically sexual species, one is inherited from each parent. "Homeology" applies to chromosomes that are related by ancestral duplication, yet segregate independently at meiosis. en.wikipedia.org/wiki/Homologous_chromosome $\endgroup$ – J-- Oct 25 '18 at 15:25
  • $\begingroup$ @canadianer Hope is the last to die... @J It's the same with ohnologs - they are also expected to segregate independently at meiosis. However "homologous chromosomes" are quite tightly linked to meiosis. $\endgroup$ – Kamil S Jaron Oct 25 '18 at 15:28
