Here's why:
* Oogenesis is the process of producing a female gamete (egg cell or ovum).
* During meiosis (cell division in oogenesis), the cytoplasm is unevenly distributed, resulting in one large cell (the egg) and one or more smaller cells called polar bodies.
* Polar bodies are essentially non-functional because they lack the necessary cytoplasm and organelles to develop into a viable egg.
* Their purpose is to get rid of extra chromosomes that are not needed in the final egg cell.
So, while a single oocyte undergoes meiosis to produce one egg cell, it also produces several polar bodies (usually three) that are eventually degraded.
