Observe the given diagram showing a specific stage of meiotic cell division.
Match List I (relative stages of this division) with List II (characteristic features) based on the diagram:
| List I | List II | ||
|---|---|---|---|
| A | Stage shown in the diagram | I | Bivalent chromosomes align on the equatorial plate |
| B | Stage preceding the diagram | II | Formation of dyad of cells |
| C | Stage succeeding the diagram | III | Crossing over between non-sister chromatids |
| D | First stage of this division | IV | Homologous chromosomes separate, sister chromatids remain associated |
Choose the correct answer from the options given below:
Options
- AA-IV, B-II, C-I, D-III
- BA-I, B-III, C-II, D-IV
- CA-I, B-IV, C-III, D-II
- DA-IV, B-I, C-II, D-III
Correct answer
D. A-IV, B-I, C-II, D-III
Step-by-step solution
Based on the given diagram, homologous chromosomes are separating and moving towards opposite poles while sister chromatids remain associated at their centromeres. This is the characteristic feature of Anaphase I of meiosis.
A. Stage shown in the diagram is Anaphase I. Its characteristic feature is that homologous chromosomes separate, but sister chromatids remain associated. (A \rightarrow IV)
B. The stage preceding Anaphase I is Metaphase I. In this stage, bivalent chromosomes align on the equatorial plate. (B \rightarrow I)
C. The stage succeeding Anaphase I is Telophase I. This stage is followed by cytokinesis, leading to the formation of a dyad of cells. (C \rightarrow II)
D. The first stage of this division is Prophase I. A key event in Prophase I (specifically pachytene) is crossing over between non-sister chromatids of homologous chromosomes. (D \rightarrow III)
Therefore, the correct matching is A-IV, B-I, C-II, D-III.
