Oogenesis is the formation of the haploid ovum from the diploid egg mother cells/ oogonia of the ovary. Oogenesis occurs in follicles of ovaries in various organisms but its period varies which supports the evidence of the basic relationship of the organisms. Oogenesis involves two biological processes as genetical programming and packaging. It usually starts before birth and complete only after the onset of puberty. So oogenesis is a discontinuous process. Only one out of 500 cells Innova stimulated by FSH which mature to form ovum. So take this quiz and know more about oogenesis.
