Question

Which among the following is a stage of meiosis during which pairs of homologous chromosomes align at the center of the cell?

• A. Anaphase II
• B. Metaphase I
• C. Prophase II
• D. Metaphase II
• E. Prophase I

Answer 1

Answer: (B)

Metaphase I

Prophase I of meiosis I is marked by synapsis of homologous chromosomes and crossing over.
Metaphase I is marked by the movement of pairs of homologous chromosomes towards the equator and their arrangement on it.
The condensation of chromatin and appearance of chromosomes with sister chromatids takes place during prophase II.
Metaphase II is marked by the arrangement of chromosomes (each with two sister chromatids) on cell's equator which is then separated by splitting of centromere and move towards opposite poles during anaphase II.

Therefore, the correct answer is option B.
