Question

Choose the correct option for the statement given below.
Statement 1 - Anaphase I of Meiosis I is characterized by splitting up of the centromere and distribution of equal number of chromosomes to the daughter cells.
Statement 2- Metaphase I of meiosis I is marked by the arrangement of homologous chromosomes assorted in two sets along the equatorial plane.

• A. Both statements are correct.
• B. Both statements are incorrect.
• C. Statement 1 is incorrect but statement 2 is correct.
• D. Statement 1 is correct but statement 2 is incorrect.

Answer 1

The correct option is C Statement 1 is incorrect but statement 2 is correct.

Anaphase I of Meiosis I results in separation of chromosomes of the homologous pair into two distinct cells. The spindle apparatus pulls the entire chromosome of the pair towards the opposite pole and hence, there is no splitting of the centromere. Therefore, statement 1 is incorrect. During Metaphase I of meiosis I homologous pairs of chromosomes arrange in two sets along the equatorial plane. Therefore, statement 2 is correct.

So, the correct answer is ‘Statement 1 is incorrect but statement 2 is correct.’
