I don't know much about virology. Is it possible for variants to 'blend'? It sounds like Omicron has a number of variations vs Delta and other major variants.

I don't know much about virology. Is it possible for variants to 'blend'? It sounds like Omicron has a number of variations vs Delta and other major variants. Is it possible that someone who is simultaneously infected with both Delta and Omicron to generate virus particles that utilize proteins from both variants in the same viral particle? If this can occur, would the genome of those viral particles get blended together, or would it just carry the genome of one or the other variants? i.e. would co-infection of multiple variants simultaneously increase mutation rate, or could hybrid variants appear?
