WebThe process of chromosome alignment differs between meiosis I and meiosis II. In prometaphase I, microtubules attach to the fused kinetochores of homologous chromosomes, and the homologous chromosomes are arranged at the midpoint of the cell in metaphase I. In anaphase I, the homologous chromosomes are separated. WebThe chromosomes are aligned midway between spindle poles during a. anaphase b. metaphase c. interphase d. prophase e. telophase; The mitotic spindle disassembles in _____: A. Prophase B. Metaphase C. Anaphase D. Telophase; During anaphase B a) kinetochore microtubules shorten. b) chromatids move towards cell poles.

WebIn synapsis, the genes on the chromatids of the homologous chromosomes are precisely aligned with each other. An exchange of chromosome segments between non-sister homologous chromatids occurs and is called crossing over. This process is revealed visually after the exchange as chiasmata (singular = chiasma) ( Figure 7.3 ). WebJul 17, 2024 · Chromosomes thicken and detach from the nuclear envelope. Similar to mitosis, the centrioles migrate away from one another and both the nuclear envelope and nucleoli break down. Likewise, the chromosomes begin their migration to the metaphase plate.
