(a)
To draw:
Four rounds of mitosis of the stem cell.
Concept introduction:
Spermatogenesis is the process where sperm cells are produced through the meiosis of the spermatogonium. Stem cells are the undifferentiated cells which can give rise to every type of cell it is found with and in the process it also gives rise to another stem cell.
(b)
To draw:
Single mitosis followed by meiosis of a spermatogonium.
Concept introduction:
Spermatogenesis is the process where sperm cells are produced through the meiosis of the spermatogonium. Stem cells are the undifferentiated cells which can give rise to every type of cell it is found with and in the process it also gives rise to another stem cell.
(c)
To determine:
What would happen if the stem cell divides like the spermatogonium.
Concept introduction:
Spermatogenesis is the process where sperm cells are produced through the meiosis of the spermatogonium. Stem cells are the undifferentiated cells which can give rise to every type of cell it is found with and in the process it also gives rise to another stem cell.

- Draw a schematic diagram showing spermatogenesis vis-à-vis oogenesis. Label the stage of development and chromosome number of daughter cells at the following levels of maturation: (a) mitotic proliferation (b) meiosis I and II (c) maturation. Table 2: Spermatogenesis vis-à-vis Oogenesis Spermatogenesis Oogenesisarrow_forwardDescribe the three major parts of a spermatozoon and state what organelles or cytoskeletal components are contained in each?arrow_forwardExamine the attached fig, which shows oogenesis in animalcells. Will the genotype of the second polar body (derivedfrom meiosis II) always be identical to that of the ootid?Why or why not?arrow_forward
- During spermatogenesis, which of the following options describes when cytokinesis would occur? Following anaphase I Following metaphase II Following telophase I Following telophase IIarrow_forwardIf there are 7 spermatogonium that will undergo cell division, how many functional spermatozoa will be formed?arrow_forwardThe process of meiosis is essential to the formation of which type of cells in the human body?arrow_forward
- Given that a diploid cell will undergo meiosis and give rise to gametes (egg or sperm cells), where in the body would you expect this cell to be located?arrow_forwardThe Human Reproductive System Discuss and compare the products of meiosis in human females and males. How many functional gametes are produced from the daughter cells in each sex?arrow_forwardHow many chromosomes would an oocyte contain if during anaphase II, the chromatids of one chromosome did not separate?arrow_forward
- If there are 7 spermatogonium that will undergo cell division, how many primary spermatozoa will be formed?arrow_forwardMale honeybees, which are haploid, produce sperm by meiosis.Explain what unusual event (compared with other animals) mustoccur during spermatogenesis in honeybees to produce sperm.Does this unusual event occur during meiosis I or meiosis II?arrow_forwardIf two sperm cells were able to fertilize the same oocyte, how many chromosomes would the zygote have?arrow_forward
