Step D is Telophase I in meiosis, where separated homologous chromosomes reach opposite poles. Nuclear envelopes form around chromatids, concluding the first division, leading to two haploid daughter cells with genetic diversity. The answer is option D.
Step D corresponds to Telophase I in meiosis, the stage following the completion of the first round of chromosome separation.
During Telophase I, the separated homologous chromosomes reach opposite poles of the cell. Nuclear envelopes begin to reform around the chromatids, resulting in the formation of two distinct nuclei.
This marks the end of the first division in meiosis, and the subsequent cytokinesis process divides the cell into two daughter cells, each with a haploid set of chromosomes. Telophase I is critical for ensuring genetic diversity in the resulting gametes, contributing to the overall process of sexual reproduction. Option D is the answer.
