lab Questions
1. Oogenesis and spermatogenesis are related in that they both ultimately produce haploid cells
and share similar meiotic and mitotic cell division, but there are significant differences between
the two. Discuss these similarities and differences below in your own words. Focus on the
timing, steps and phases of these processes in order to compare and contrast them. (Hint: Your
response should be 6-10 sentences in length.)
The development of haploid cells for sexual reproduction is called gametogenesis. Both
oogenesis and spermatogenesis share the beginning steps of mitotic divisions, but other
differences such as the order of events and results are present. Whereas spermatogenesis
continues, beginning at adolescence, throughout the life of a man, oogenesis starts during fetal
development and ends after puberty. The one viable egg and three polar bodies are generated
during oogenesis, and four viable sperm cells are obtained during spermatogenesis. During
oogenesis, there is unequal division of the cytoplasm among the egg and polar bodies as the
meiotic divisions take place unequally. Meiotic divisions allow the sperms to have uniform sizes
and functionality in the process of spermatogenesis. Meiosis II is finished during
spermatogenesis, whereas in oogenesis it is only finished when fertilized. This is another
distinction between the two processes. The site of both processes is also clearly distinct;
oogenesis occurs in the ovaries, whereas seminiferous tubules in the testes.
