A researcher is studying mitosis in a novel diploid organism with 2n = 16 chromosomes. During metaphase, a drug is applied that inhibits the separation of sister chromatids but allows the cell to progress through anaphase and telophase. At the end of this aberrant cell division, what is the most likely chromosomal composition of the resulting daughter cells?
Two diploid cells (2n=16) each
One diploid cell (2n=16) and one cell with no chromosomes
One tetraploid cell (4n=32)
Two cells with 8 chromosomes each
