> checking one of the cells at the 16 or 32 cell stage

I wonder: How is an embryo dealing with missing a cell at this early? Does this error compound after a few doublings (embryo is smaller)?

AFAIK it shouldn't be issue. Some twins (identical twins) are created when a two cell organism detaches into two separate entities.

It doesn't seem to lead to any harms when done as part of preimplantation genetic diagnosis in general, so this specific case shouldn't be too bad.
