Step 1:Let's solve this step by step:
Step 2:: Understanding Meiosis
Meiosis is a type of cell division that produces gametes (sex cells) with half the number of chromosomes as the parent cell. It involves two sequential cell divisions: meiosis 1 and meiosis 2.
Step 3:: Telophase 2 Characteristics
During telophase 2, the final stage of meiosis 2, several key events occur: - The chromosomes have already separated in anaphase 2 - Nuclear membranes reform around the separated chromosomes - Cytokinesis (cell division) occurs
Step 4:: Analyzing the Possible Answers
A. DNA doubles to produce sister chromatids - Incorrect: DNA doubling occurs before meiosis, during interphase B. A total of four daughter cells form - Correct! At the end of meiosis, four haploid daughter cells are produced C. Two diploid cells are produced - Incorrect: The cells produced are haploid, not diploid D. The mitotic spindle forms - Incorrect: The spindle forms earlier, during metaphase 2
Final Answer
A total of four daughter cells form during telophase 2 of meiosis.
