A student encounters an animal embryo at the eight-cell stage. The four smaller cells that comprise one hemisphere of the embryo seem to be rotated 45 degrees and lie in the grooves between larger, underlying cells (spiral cleavage). If we were to separate these eight cells and attempt to culture them individually, then what is most
likely to happen?

#SCPH28 | Zoology

All eight cells will die immediately.
Each cell may continue development, but only into an inviable embryo that lacks many parts.
Each cell may develop into a full-sized, normal embryo.
Each cell may develop into a smaller-than-average, but otherwise normal, embryo.
