The phase where sister chromatids separate.Group of answer choicesmeiosis Iboth mitosis and meiosis Iboth mitosis and meiosis 11mitosismeiosis II

To answer the question about the phase in which sister chromatids separate, let's analyze the relevant processes involved in cell division.

Breakdown of the Question

1. Understand the definition of sister chromatids.
2. Identify the phases of mitosis and meiosis where sister chromatids separate.

Relevant Concepts

• Mitosis: The process of cell division that results in two genetically identical daughter cells.
• Meiosis: A specialized type of cell division that reduces the chromosome number by half and produces four genetically diverse gametes.

Analysis of Each Phase

1. Mitosis:

   • During anaphase, sister chromatids are pulled apart to opposite poles of the cell.

2. Meiosis:

   • In meiosis I, homologous chromosomes are separated, not sister chromatids.
   • In meiosis II, it is similar to mitosis, where sister chromatids are separated during anaphase II.

Verify and Summarize

• In both mitosis and meiosis II, the critical phase for the separation of sister chromatids is anaphase.

Final Answer

The correct choice is both mitosis and meiosis II, as sister chromatids separate during anaphase in both processes.
