Multiple Choice

Which description is true for a secondary oocyte?

It is a diploid cell that has completed meiosis I and is arrested in prophase I.

It is a diploid cell that has completed meiosis II and is ready for fertilization.

It is a haploid cell that has completed meiosis II and is ready for fertilization.

It is a haploid cell that has completed meiosis I and is arrested in metaphase II until fertilization.

Verified step by step guidance

Understand the process of oogenesis, which is the development of female gametes or ova. It involves several stages, including the formation of primary and secondary oocytes.

Recall that meiosis is a type of cell division that reduces the chromosome number by half, resulting in haploid cells. It consists of two stages: meiosis I and meiosis II.

Recognize that a secondary oocyte is formed after the completion of meiosis I. During meiosis I, the primary oocyte divides to form a secondary oocyte and a polar body, both of which are haploid.

Note that the secondary oocyte is arrested in metaphase II. This means it pauses in the middle of meiosis II and will only complete meiosis II if fertilization occurs.

Conclude that the correct description of a secondary oocyte is that it is a haploid cell that has completed meiosis I and is arrested in metaphase II until fertilization.
