Question

Which sequence correctly represents the order of events during egg formation?
a) primary oocyte ® secondary oocyte ® meiosis I ® meiosis II ® ovum
b) ovum ® meiosis I ® primary oocyte ® meiosis II ® secondary oocyte
c) primary oocyte ® meiosis I ® secondary oocyte ® meiosis II ® ovum
d) primary oocyte ® meiosis I ® ovum ® meiosis II ® secondary oocyte

Answer 1

Answer:

The correct option is c) primary oocyte ® meiosis I ® secondary oocyte ® meiosis II ® ovum

Explanation:

• In the process of cell division, primary oocyte can be described as the oocyte that results from the development of oogonium.
• After the first meiotic division, the oocyte give rise to the secondary oocyte and the polar body.
• After meiosis part II ovum is produced.
• Hence, the correct sequel is shown in option c) primary oocyte ® meiosis I ® secondary oocyte ® meiosis II ® ovum
