During oogenesis, polar bodies are formed through a process called meiosis. Meiosis is a type of cell division that results in the production of gametes, such as eggs. As the egg cell undergoes meiosis, it divides into four cells, with three of them becoming polar bodies. These polar bodies contain extra genetic material and eventually disintegrate, leaving behind a single functional egg cell with the necessary genetic material for fertilization.
What else can I help you with?
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 are polar bodies used for in the process of oogenesis?
Polar bodies are small cells produced during oogenesis that do not have the ability to develop into a mature egg. They are formed as a byproduct of the egg cell division process and help to ensure the proper distribution of genetic material.
What happens to the polar body during the process of oogenesis?
During oogenesis, the polar body is a small cell that is formed as a byproduct when the egg cell divides. The polar body typically does not have the ability to develop into a mature egg cell and eventually disintegrates.
In animals polar bodies are formed as a result of what?
Polar bodies are formed during oogenesis as a result of unequal cytokinesis, where the cytoplasm is unevenly divided during the cell divisions that give rise to eggs. These polar bodies do not have the ability to develop into offspring but help to provide nutrients to the developing egg cell.
What is an ootid?
An ootid is a cell formed during oogenesis in the final stages of egg development. It is the product of the meiosis process in the female reproductive system and eventually develops into a mature egg after fertilization.

What it oogenesis?
That is the process by which eggs are formed.
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.

How many polar bodies are produced during spermatogenenis?
both polar bodies have the same amount of chromosomes. which would be just diploid so 23, because its a gamete and therefore is half the normal amount. so yeah, 23 chromosomes in the first polar body.
How many egg cells are produced in gametogenesis?
Also called oogenesis, there is only 1 formed and 3 polar bodies which are destroyed by the body
What is the process by which ova are formed?
Ova are formed through a process called oogenesis, which begins with the development of oogonia (early ova) in the ovaries. Oogonia undergo mitotic division to produce primary oocytes, which then undergo meiosis to form secondary oocytes. These secondary oocytes are released during ovulation and, if fertilized, develop into mature ova.
What is an ootid?
An ootid is a cell formed during oogenesis in the final stages of egg development. It is the product of the meiosis process in the female reproductive system and eventually develops into a mature egg after fertilization.
What are some unequal cytoplasmic divisions are characteristic of?
Unequal cytoplasmic divisions are characteristic of oogenesis, where a large ovum receives most of the cytoplasm while smaller polar bodies are formed, which eventually degenerate. Unequal divisions also occur during embryonic development in organisms such as nematodes, where specific cells receive an unequal distribution of cytoplasm to establish asymmetric cell fates.
When does crossing over occur for oogenesis?
Crossing over occurs during prophase I of meiosis I in oogenesis, which is when homologous chromosomes exchange genetic material. This process increases genetic diversity by shuffling genetic information between maternal and paternal chromosomes.
