Question

What do you suppose happened during meiosis in individuals possessing an odd number of chromosomes? Explain.

Answer 1

Answer:

There are 2 parts of cell cycle:

interphase and mitosis/meiosis.

Interphase can be future subdivided into growth 1 (G1), synthesis (s), and growth 2 (G2) . During the G phase , the cell grows by producing various proteins ,and during the S phase ,the DNA is replicated so that each chromosome contains 2 identical sister chromatids (c)

Meiosis contains 4 phases:

1. prophase,
2. metaphase
3. anaphase
4. telophase

• In prophase , the nuclear envelope break down , and chromatin condenses into chromosomes .
• In metaphase,the chromosome line of along the metaphase plate, and microtubules attach to the kinetochores of each chromosome.
• In anaphase, the chromatids separated and are pulled by the microtubules to opposite end of the cell
• In the telophase ,the nuclear envelope reappear, the chromosome unwind into chromatin , and the cell undergoes cytokinesis, which splits the cell into 2 identical daughter cells.
