Polar bodies refer to cell structures that are located inside an ovum of both plants and animals. They are formed due to asymmetrical cell division. Polar bodies are formed during oogenesis. It is a process by which an ovum egg is created in the ovarian follicle of the ovary. Thus it is a by-product of meiosis in females. It contains cytoplasm and is formed with the oocyte. They are discarded or degenerate after a period of time.
There are one or two polar bodies inside the ovum. During meiosis an oocyte divides and one part becomes the ovum while the other develops into polar bodies. Due to progress of science polar bodies can be used to diagnose the genetic status of the egg. It is also used to understand and determine the genetic contribution of a mother to the embryo.
