Multiple Choice
During telophase I of meiosis, which event most directly occurs?
A
Homologous chromosomes arrive at opposite poles, nuclear envelopes may reform, and cytokinesis often begins, producing two haploid cells with sister chromatids still joined.
B
Crossing over occurs between non-sister chromatids of homologous chromosomes.
C
Sister chromatids separate at the centromeres and move to opposite poles.
D
Chromosomes align individually along the metaphase plate with sister chromatids attached to opposite spindle poles.
Verified step by step guidance1
Identify the stage of meiosis in question: telophase I, which is the final phase of meiosis I.
Recall that during meiosis I, homologous chromosomes (each consisting of two sister chromatids) are separated, unlike meiosis II where sister chromatids separate.
Understand that at telophase I, homologous chromosomes have already been pulled to opposite poles of the cell.
Recognize that nuclear envelopes may reform around these sets of chromosomes, and cytokinesis (the division of the cytoplasm) often begins, resulting in two haploid cells.
Note that sister chromatids remain joined at this stage, meaning they have not yet separated, which will occur later during meiosis II.
