After the first meiotic division of primary oocyte (2n), a tiny first polar body (polocyte) and secondary oocyte (n) are formed. At present, we are not certain whether the first polar body born out of first meiosis divide further or degenerate. If it divides (mitotically), then two secondary polar bodies are formed.
In humans and most vertebrate the first polar body does not undergoes meois 2 ( sometimes goes to meosis 2 and form the polar body), whereas secondary oocyte produced at true metaphase 2 and stop at this stage and wait spermatozoa to further completion.
How many polar bodies are formed during oogenesis in humans? After the first meiotic division of primary oocyte (2n), a tiny first polar body (polocyte) and secondary oocyte (n) are formed. At present, we are not certain whether the first polar body born out of first meiosis divide further or degenerate.

Polar body – Wikipedia
A polar body is a small haploid cell that is formed at the same time as an egg cell during oogenesis, but generally does not have the ability to be fertilized.. When certain diploid cells in animals undergo cytokinesis after meiosis to produce egg cells, they sometimes divide unevenly. Most of the cytoplasm is segregated into one daughter cell, which becomes the egg or ovum, while the smaller …
