C
Telophase I
D
Metaphase I
Verified step by step guidance1
Understand the concept of synapsis: Synapsis is the pairing of homologous chromosomes during meiosis, which is crucial for genetic recombination.
Review the stages of meiosis: Meiosis consists of two main divisions, Meiosis I and Meiosis II, each with several phases: Prophase, Metaphase, Anaphase, and Telophase.
Focus on Prophase I: During Prophase I of Meiosis I, homologous chromosomes pair up in a process called synapsis, forming structures known as tetrads.
Consider the significance of Prophase I: This phase is essential for crossing over, where genetic material is exchanged between homologous chromosomes, increasing genetic diversity.
Eliminate other options: Anaphase I, Telophase I, and Metaphase I do not involve synapsis. Anaphase I involves the separation of homologous chromosomes, Telophase I involves the completion of the first meiotic division, and Metaphase I involves the alignment of tetrads at the cell's equator.
