NCERT · Class 11 · Biology · Cell Cycle and Cell DivisionDuring anaphase-I of meiosis:
Step-by-Step Solution
During anaphase-I, homologous chromosomes separate and move to opposite poles, while sister chromatids remain associated at their centromeres, resulting in reduction of chromosome number.
Detailed Options Breakdown
Option : Sister chromatids separate
Incorrect choice. This distractor represents a common misunderstanding of the core principles of Cell Cycle and Cell Division.
Option 1: Homologous chromosomes separate (Correct Answer)
Correct choice. Refer to the step-by-step verified solution guidelines above for details.
Option 2: Non-homologous chromosomes fuse
Incorrect choice. This distractor represents a common misunderstanding of the core principles of Cell Cycle and Cell Division.
Option 3: Centromeres do not split at all
Incorrect choice. This distractor represents a common misunderstanding of the core principles of Cell Cycle and Cell Division.
