|  | 1. | In plants, oogenesis occurs inside the female gametophyte via mitosis. 
 
 | 
|  | 2. | Primary oocytes will undergo oogenesis in which they enter meiosis. 
 
 | 
|  | 3. | Oogenesis is greatly affected by pollen intake. 
 
 | 
|  | 4. | NBS1 mutant mice display cellular radiation sensitivity and female mice are sterile due to oogenesis failure. 
 
 | 
|  | 5. | Her two years of education and research concerning the oogenesis of frog eggs consummated a Sorbonne. 
 
 | 
|  | 6. | Thus, spermatogenesis is the male version of gametogenesis, of which the female equivalent is oogenesis. 
 
 | 
|  | 7. | In females, gametogenesis is known as oogenesis which occurs in the ovarian follicles of the ovaries. 
 
 | 
|  | 8. | In mammalian and human fetal oogenesis all developing oocytes develop to this stage and are arrested before birth. 
 
 | 
|  | 9. | Oogenesis occurs within the embryo sac and leads to the formation of a single egg cell per ovule. 
 
 | 
|  | 10. | The initiation of oogenesis occurs from August to February and the eggs take about 18 months to mature.
