The answer is yes. Female infants are born with primary oocytes that are stalled in prophase I until puberty. At the onset of puberty, the ovaries begin oogenesis. During oogenesis, three polar bodies and one functional gamete are produced. Oogenesis is achieved through meiosis. However, the ovulated secondary oocyte arrests in metaphase II and does not complete meiosis II until it is fertilized.
No, meiosis in females completes when the oocyte is ovulated, regardless of whether fertilization occurs. If fertilization occurs, the second stage of meiosis is completed by the fusion of the oocyte with a sperm cell. If fertilization does not occur, the oocyte degenerates and is eventually expelled from the body during menstruation.

When will a secondary oocyte complete meiosis II?
A secondary oocyte will complete meiosis II after fertilization by a sperm cell.
When does meiosis 2 occur in females during the reproductive process?
Meiosis 2 occurs in females during the reproductive process after fertilization, when the secondary oocyte completes its division to form a mature ovum and a polar body.
In what phase of meiosis is a secondary oocyte arrested?
A secondary oocyte is arrested in the metaphase II phase of meiosis.
In which stage is a primary oocyte arrested?
A primary oocyte is arrested in the prophase stage of meiosis I.
What is the difference between ovum and secondary oocyte?
An ovum is a mature female reproductive cell that has completed meiosis. A secondary oocyte is an intermediate stage in meiosis that occurs during ovulation and has not yet completed meiosis.
When will a secondary oocyte complete meiosis II?
A secondary oocyte will complete meiosis II after fertilization by a sperm cell.
When does an oocyte complete meiosis II?
An oocyte completes meiosis II after it is fertilized by a sperm cell. This process results in the formation of a mature ovum (egg) with a haploid set of chromosomes.
Is Oocyte haploid?
Unfertilized egg is haploid; but fertilized egg is diploid. That is why you sometimes see chickens even in commercial eggs.
How many functional ova are produced at the end of one complete cycle of meiosis?
In females, one functional ovum is produced at the end of one complete cycle of meiosis. Meiosis I produces a secondary oocyte, and meiosis II forms a mature ovum (egg cell) after fertilization.
When does meiosis 2 occur in females during the reproductive process?
Meiosis 2 occurs in females during the reproductive process after fertilization, when the secondary oocyte completes its division to form a mature ovum and a polar body.
In what phase of meiosis is a secondary oocyte arrested?
A secondary oocyte is arrested in the metaphase II phase of meiosis.
When a primary oocyte divides a secondary oocyte and what are produced?
A primary oocyte divides into a secondary oocyte and a polar body during meiosis I. The secondary oocyte undergoes meiosis II to produce a mature ovum (egg) and another polar body.
In which stage is a primary oocyte arrested?
A primary oocyte is arrested in the prophase stage of meiosis I.
When the primary oocyte divides a secondary oocyte and what else is produced?
The primary oocyte divides into a secondary oocyte and a polar body during meiosis I. The secondary oocyte then goes through meiosis II to produce a mature ovum (egg) and another polar body.
What is the difference between ovum and secondary oocyte?
An ovum is a mature female reproductive cell that has completed meiosis. A secondary oocyte is an intermediate stage in meiosis that occurs during ovulation and has not yet completed meiosis.
The cell resulting from meiosis in either males or females are called?
The cell resulting from meiosis in males is called spermatids, which will further mature into sperm cells. In females, the cell resulting from meiosis is called a secondary oocyte, which will later develop into an egg upon fertilization.
What is period of ovum?
an ovum mature oocyte after meiosis division
