(biology) The formation and development of an oocyte or ovum
Oogenesis is the process of the production of egg cells that takes places in the ovaries
(biology) The formation and development of an oocyte or ovum
Diagram showing the reduction in number of the chromosomes in the process of maturation of the ovum. (In mammals, the first polar body normally disintegrates before dividing, so only two polar bodies are produced.)
(biology) The formation and development of an oocyte or ovum
Oogenesis in eukaryotic cells. (A) oogonium where the mitotic division occurs (B) differentiation and meiosis I begins (C) primary oocyte (D) meiosis I is completed and meiosis II begins (E) secondary oocyte (F) first polar body (G) ovulation must occur and the presence of the sperm penetration (fertilization) induces meiosis II to completion (H) ovum (I) second polar body
