Meiosis-I is also called as heterotypic division/reductional cell division. Select the correct option by comparing the phase of the meiosis and their respective events from lists I and II. List I (Phase of meiosis) List II (Event that occurs) 1. Prophase I Crossing over occurs 2. Metaphase I Sister chromatids migrate to opposite poles 3. Anaphase I Homologous chromosomes line up at equator in pairs
Options
- A1, 2 and 3 are correct
- B1 and 2 are correct, 3 is false
- C1 is correct, 2 and 3 are false
- D1 and 3 are correct, 2 is false
Correct answer
C. 1 is correct, 2 and 3 are false
Step-by-step solution
Crossing over is the exchange of genetic material between homologous chromosomes which occurs during prophase I of meiosis during a process called a synopsis. During metaphase, the homologous chromosomes line up at the equator in pairs and in anaphase, the sister chromatids migrate towards opposite poles.
