Question

The number of chromosome groups at the equatorial plate in metaphase I of meiosis, in a plant with diploid (2n) chromosome number equal to 50 shall be

• A. 50
• B. 25
• C. 30
• D. 100

Answer 1

Answer: (B)

25

The first division of meiosis is characterized by pairing between homologous chromosomes and exchange of segments between them, so that if the normal diploid number is 50, 25 chromosome groups or 25 pairs are expected to be seen in metaphase I.

So, the correct answer is option B.
