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.
How many egg cells come form a female germ cell?
One primary oocyte divides by meiosis and produces one polar body and one secondary oocyte. The polar body goes on to produce two more polar bodies, and the secondary oocyte divides into one polar body and one ovum. Therefore, one cell is produced from one primary oocyte.
Which type of cell is produced by meiosis in a male organism?
Secondary spermatocyte
Is It the secondary oocyte and not the egg that the sperm fertilizes?
Yes, it is the secondary oocyte that the sperm fertilizes. The secondary oocyte completes meiosis II to become a mature egg only after fertilization.
Is the polar body a haploid cell?
Yes, polar bodies are haploid cells. They are produced during oogenesis when the cytoplasm of the primary oocyte is unequally divided during meiosis, resulting in one large secondary oocyte and two smaller polar bodies.
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.
How many egg cells come form a female germ cell?
One primary oocyte divides by meiosis and produces one polar body and one secondary oocyte. The polar body goes on to produce two more polar bodies, and the secondary oocyte divides into one polar body and one ovum. Therefore, one cell is produced from one primary oocyte.
Compare and contrast Primary oocyte and secondary oocyte?
Primary oocytes are diploid cells that have undergone DNA replication but are arrested in prophase I of meiosis, whereas secondary oocytes are haploid cells resulting from the division of primary oocyte after completing meiosis I. Secondary oocytes are arrested in metaphase II and are released during ovulation, while primary oocytes are present in the ovaries prior to puberty.
Which type of cell is produced by meiosis in a male organism?
Secondary spermatocyte
How many eggs are produced from one oocyte?
one cell is produced from one primary oocyte.
During cytokinesis in a female what divides unequally?
During cytokinesis in a female, the cytoplasm divides unequally, resulting in one large cell (the secondary oocyte) and one small cell called the polar body. This unequal division helps ensure that the secondary oocyte retains most of the cytoplasm and organelles needed for further development, while the polar body eventually disintegrates.
How many human eggs could potentially be produced from 10 primary oocytes?
One cell is produced from one primary oocyte. Therefore 10 eggs can be potentially produced from 10 primary oocytes.
Is It the secondary oocyte and not the egg that the sperm fertilizes?
Yes, it is the secondary oocyte that the sperm fertilizes. The secondary oocyte completes meiosis II to become a mature egg only after fertilization.
Prenatal maturation of oocyte?
Primordial, secondary, tertiary, and antral are the basic steps in a developing oocyte
Is the polar body a haploid cell?
Yes, polar bodies are haploid cells. They are produced during oogenesis when the cytoplasm of the primary oocyte is unequally divided during meiosis, resulting in one large secondary oocyte and two smaller polar bodies.
Difference between primary and secondary oocyte?
Any oogonia that has arrested itself in meiosis I prophase-dipotene on the onset of OMI (oocye maturation inhibition) hormone in the 3rd month of pregnancy and there after is a primary oocyte. On the urge of Leutinizing hormone which induces the pre-ovulatory phase, the primary oocyte completes meiosis I and arrests itself in meiosis II metaphase, which would only be completed if fertilization occurs, otherwise it will degenrate in 24 hours. On the completion of meiosis I, a SECONDARY oocyte and forst polar body is going to be formed.
How do oogenesis?
Oogenesis is the process by which female gametes (eggs) are produced. It begins with the differentiation of oogonia (stem cells) into primary oocytes, followed by meiosis I to form secondary oocytes. The secondary oocyte completes meiosis II upon fertilization to produce a mature ovum.
