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

In an experiment, cells are arrested in metaphase using colchicine, a drug that inhibits microtubule polymerization. If these cells are then fused with cells in G1 phase, what is the most likely outcome for the G1 chromosomes?
The G1 chromosomes will replicate their DNA.
The G1 chromosomes will condense prematurely.
The G1 chromosomes will remain unaffected.
The G1 chromosomes will fragment.
