Ques: Answer the following question given this paragraph: Oogenesis begins long before birth when an oogonium with the diploid number of chromosomes undergoes mitosis. It produces a diploid daughter cell called a primary oocyte. The primary oocyte, in turn, starts to go through the first cell division of meiosis (meiosis I). However, it does not complete meiosis until much later. The primary oocyte remains in a resting state, nestled in a tiny, immature follicle until puberty. Q: What begins when an oogonium with the diploid number of chromosomes undergoes mitosis? Choices: - germination - morphogenesis - gametogenesis - oogenesis A:
Ans: oogenesis
