A polar body is a small cell produced during the process of meiosis in females. It contains genetic material but does not develop into a mature egg. Polar bodies are formed as a result of unequal division of genetic material during meiosis, which helps ensure that the egg cell receives the necessary genetic material for fertilization.
What else can I help you with?
What is a polar body and how does it relate to the process of oogenesis?
A polar body is a small cell produced during the process of oogenesis, which is the formation of female gametes (eggs). Polar bodies are created during meiosis, a type of cell division that reduces the chromosome number by half. They do not have the ability to develop into a viable egg, but they help in the distribution of genetic material and ensure the proper division of chromosomes during oogenesis.
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.
Small cell resulting from meiosis in female animals which usually does not participate in reproduction?
The small cell resulting from meiosis in female animals is known as a polar body. It typically does not participate in reproduction and eventually degenerates or is absorbed by the body. Its main function is to ensure that the larger egg cell receives most of the cytoplasm and organelles during meiosis.
What is the size of a polar body?
a polar body is A small cell (which eventually disintegrates) that is the by-product of meiosis in female animals. One functional ovum and potentially three polar bodies result from meiosis of each primary oocyte. By:hyden 252-1079 im bored
What happens to the polar bodies formed during oogenesis?
During oogenesis, polar bodies are formed as a result of unequal division of cytoplasm during meiosis. These polar bodies do not have the ability to develop into a mature egg cell and eventually disintegrate or are reabsorbed by the body.
What is the largest polar body of meiosis called?
First polar body

What is a chromosome repository in meiosis?
polar body
Small cell formed and thens dies during meiosis in a female is?
A polar body. It is formed during the process of oogenesis when a primary oocyte undergoes meiosis to produce one egg cell and three polar bodies. The polar bodies are small cells that contain genetic material but eventually degenerate and are not fertilized.
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.
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.
Why is a second polar body expelled after fertilisation?
The second polar body is expelled after fertilization as a result of the completion of meiosis in the oocyte. When a sperm fertilizes the egg, it triggers the final stages of meiosis, leading to the division of the oocyte into a mature ovum and the second polar body. This process ensures that the egg retains the correct haploid number of chromosomes while discarding the excess genetic material. The expulsion of the polar body is crucial for maintaining genetic balance in the resulting zygote.
Does polar body formation occur in meiosis in males?
Polar bodies are made in the female. Through the process of oogenesis, a primary oocyte goes through Meiosis I and Meiosis II. Of the four cells created, one cell gets the most cytoplasm and is more likely to survive. This egg is called the "ovum". The other three cells which are not made are called polar bodies.

The small cell resulting from meiosis in female animals is known as a polar body. It typically does not participate in reproduction and eventually degenerates or is absorbed by the body. Its main function is to ensure that the larger egg cell receives most of the cytoplasm and organelles during meiosis.
During which type of gametogenesis would you see polar bodies?
oogenesisMeiosis I and Meiosis IIPolar Body are porduced in the process of Egg or ovum (female Side).
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 Ultimate fate of the polar body?
The polar body created during meiosis will actually DIE. It works as sort of a "sacrificial lamb" to secure the survival of the egg cell.
