Oogenesis

Some cells of ovary prepare structures called follicles, in which many diploid oogonia are present.
Some oogonia produce diploid primary oocytes.
 One of the primary oocytes completes meiosis-I and produces two haploid cells. The smaller
cell is called first polar body and the larger one is called secondary oocyte. The secondary oocyte
completes meiosis-II and produces two haploid cells i.e. a second polar body and an egg cell.
