Textbook Question
Chapter 9, Problem 8WIO
In some animals, females can reproduce by themselves—that is, without males. In this process, called parthenogenesis, the young develop from unfertilized eggs. Use the Internet to find a species that uses parthenogenesis. How does parthenogenesis work in that species? What are the differences between meiosis in that species and the events of “typical” meiosis?

If gametes had the same number of chromosomes as body cells, and an organism had 24 chromosomes in its body cells, how many chromosomes would it have after three generations? How does this illustrate the necessity of meiosis for gamete formation?
One of the advantages of sexual reproduction is that it promotes genetic diversity in the offspring. This is because gametes are produced by meiosis, which introduces genetic variation into the resulting gametes. How does meiosis accomplish this? Describe one way (there are several choices) in which meiosis produces new combinations of genes in gametes.
Male 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?

What is the chromosomal content of the final product? Why must this occur to make a chromosomally viable human?arrow_forwardIf a human gamete with a missing chromosome participates in fertilization with a gamete with a normal number of chromosomes, how many chromosomes will the zygote have?

- Which statement does not accurately describe what occurs during the process of meiosis? A) All stages of meiosis follow DNA replication. B) Meiosis produces gametes with the haploid chromosome number. C) Meiosis produces four identical gametes, either egg or sperm. D) Genetic variation among sexually reproducing organisms is enhanced by meiosis. Not Gradedarrow_forwardIn human spermatogenesis, mitosis of a stem cell gives rise to one cell that remains a stem cell and one cell that becomes a spermatogonium. Draw four rounds of mitosis for a stem cell and label; the daughter cells. 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. What would happen if stem cells divided like spermatogonia?arrow_forwardHow would the mutation of a single chromosome in metaphase 1 of meiosis affect the process of meiosis?
