Select the correct answer regarding the phase of meiosis and their respective events using the lists given below: List I (Phase of meiosis) List II (Event over occurs) (1) Prophase I Crossing over occurs (2) Metaphase II Sister chromatids migrate to opposite poles (3) Anaphase I Homologous 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 and is called synapsis. The homologous chromosomes line at equator in pairs during metaphase I and the sister chromatids migrate towards opposite poles during anaphase I.
