Question
Chapter 25, Problem 29RQ
Summary Introduction
To review:
The differences between oogenesis and spermatogenesis with respect to the number of gametes produced from each primary oocyte and spermatocyte and the period during which mitosis of the stem cell occurs.
Introduction:
The continuation of sexually reproducing species is assured by the formation of a single-celled zygote from two gamete cells. The haploid male and female gamete give rise to a single-celled diploid zygote. The sperm is designated as the male gamete while the ovum/egg is termed as the female gamete.

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
Oogenesis
In human spermatogenesis, mitosis of a stem cell gives rise to one cell that remains a stem cell and one cell that becomes a spermatogonium. (a) Draw four rounds of mitosis for a stem cell, and label the daughter cells. (b) For one spermatogonium, draw the cells it would produce from one round of mitosis followed by meiosis. Label the cells, and label mitosis and meiosis. (c) Explain what would happen if stem cells divided like spermatogonia.
If one follows 50 primary oocytes in an animal through theirvarious stages of oogenesis, how many secondary oocytes wouldbe formed? How many first polar bodies would be formed? Howmany ootids would be formed? If one follows 50 primary spermatocytes in an animal through their various stages of spermatogenesis, how many secondary spermatocytes would beformed? How many spermatids would be formed?

- Reproductive physiology (human) a) At the time of ovulation, the released ovum (egg) has completed both meiosis I and meiosis II. b) Because the corpus luteum (CL) is rescued from atresia by hCG early in pregnancy, the CL continues to produce progesterone throughout the 9 months of a normal pregnancy. c) Late in the follicular phase, estrogen participates in a positive feedback loop that leads to a surge in luteinizing hormone and ovulation. d) Both (a) and (b) are correct and (c) is incorrect e) Statements (a), (b) and (c) are all correctarrow_forwardOogenesis in the female results in one functional gamete—the egg, or ovum. What other cells are produced? What is the significance of this rather wasteful type of gamete production—that is, production of a single functional gamete instead of four, as seen in males?arrow_forwardSpermatogenesis and oogenesis both involve meiosis but differ in significant ways. One of those differences include what? A) Cytokinesis is unequal in spermatogenesis B) Production of sperm is continuous; in humans, and the number of future egg cells is set at birth C) Oogenesis is an uninterrupted sequence, but there are long delays in spermatogenesis D) All of the abovearrow_forward
- Describe the development of reproductive organs in a fetus of each gender. Which genes, gene products, and hormones are involved in the sex differences? Which sex- related hormones are circulating in high concentrations in a pregnant woman compared to a nonpregnant woman? Do these hormones cross the placenta (if you are uncertain, consider hormone chemical class relative to membrane permeability to make an educated guess)? Assuming these hormones do cross the placenta, how do they affect the hormonal environment inside the fetus, and how does this relate to fetal reproductive development?arrow_forwardWhy is a second polar body expelled after fertilisation? a) To remove excess cytoplasm b) Because the oocyte must reactivate the incomplete meiosis before fusing with the sperm c) Before fusion with the sperm it must complete mitosis d) The fertilised oocyte is not a haploid cell until it expels the sperms mitochondriaarrow_forwardHow do the haploid cells arising from oogenesis differ structurally and functionally from those arising from spermatogenesis?arrow_forward
- Name the stages of spermatogenesis from spermatogonium to spermatozoa. How do they differ in the number ofchromosomes per cell and chromatids per chromosome?arrow_forwardExplain how a spermatogonium, containing a diploid number of chromosomes, develops into four functional sperm, each containing a haploid number of chromosomes. In what significant way(s) does oogenesis differ from spermatogenesis?arrow_forwardWhat stimulates the completion of meiosis Il in a secondary oocyte? O a) A surge of Follicle-Stimulating Hormone (FSH) following the degeneration of the corpus luteum O b) A surge of Luteinising Hormone (LH) on day 13 of the menstrual cycle O) Sperm-egg binding at fertilisation d) Sperm-zona pellucida binding at fertilisationarrow_forward

Cytokinesis is unequal in oogenesis whereas it i equal in spermatogenesis 2.) spermatogenesis is not completed until after fertilization occurs, but oogenesis is completed by the time a girl is born 3.) Oogenesis produces four haploid cells, whereas spermatogenesis produces only one functional spermatozoon 4.) Oogensis ends at menopause. Whereas spermatogenesis is finished before birth 5.)
