Which is true of a secondary oocyte during meiosis?
A
It is formed after the first meiotic division and contains a polar body.
B
It is haploid and contains 46 chromosomes.
C
It completes meiosis II before ovulation.
D
It is arrested in metaphase II until fertilization occurs.
Verified step by step guidance1
Understand the process of oogenesis, which is the development of the female gametes or oocytes. It involves two meiotic divisions: meiosis I and meiosis II.
During oogenesis, a primary oocyte undergoes the first meiotic division to form a secondary oocyte and a polar body. This division reduces the chromosome number by half, making the secondary oocyte haploid.
Recognize that the secondary oocyte is arrested in metaphase II of meiosis. This means it pauses its division process at this stage and will not complete meiosis II unless fertilization occurs.
If fertilization occurs, the secondary oocyte will complete meiosis II, resulting in the formation of an ovum and another polar body.
Review the options given: The secondary oocyte is indeed arrested in metaphase II until fertilization, which aligns with the correct answer provided.
