Answer 1

Without the specific figure or context of "Figure 9-6," I can't provide a definitive answer. However, I can explain the terms generally used in genetics:

- **Tetrad**: This refers to a group of four chromatids formed during meiosis when homologous chromosomes pair up.

- **Synapsis**: This is the stage during prophase I of meiosis where homologous chromosomes pair tightly.

- **Crossing over**: This is the process that occurs during prophase I of meiosis where homologous chromosomes exchange genetic material.

- **Daughter chromosomes**: These are the chromosomes that are produced when replicated chromosomes (sister chromatids) are separated during cell division.

If you can provide more context or details about the figure, I can help you identify the structure labeled X in stage A.
