Question
Chapter 9, Problem 2WIO
Summary Introduction
To determine:
The significance of having two sets of chromosomes to meiosis.
Introduction:
Meiosis divides the cell twice and produces four daughter cells. It reduces the number of chromosomes by half. This process is primarily responsible for the production of “

Most cells in a sexually reproducing organism have two sets of chromosomes. Explain this observation and describe its significance to meiosis.
In a description of meiosis the terms ‘chromosome’ and ‘chromatid’ may be used. Distinguish between these two terms.
There are 56 chromosomes in a mature elephant cell. If one of the elephants cells responsible for gamete production undergoes meiosis, how many chromosomes would be present in each cell after meiosis I, and then after meiosis II. Explain your reasoning.
A sperm cell from the fruit fly Drosophila melanogaster contains four chromosomes. How many chromosomes would be present in a spermatogonial cell about to enter meiosis? How many chromatids would be present in a spermatogo- nial cell at metaphase I of meiosis? How many would be present at metaphase II?

- Explain how the random alignment of homologous chromosomes during metaphase I contributes to variation in gametes produced by meiosis.arrow_forwardHuman haploid gametes (sperm and eggs) contain: a. 46 chromosomes, 46 chromatids b. 46 chromosomes, 23 chromatids c. 23 chromosomes, 46 chromatids d. 23 chromosomes, 23 chromatidsarrow_forwardDuring which phases of the mitotic cycle would the terms chromosome and chromatid refer to identical structures?arrow_forward
- It is possible that an alternative mechanism for generating germ cells could have evolved. Consider meiosis in a germ cell precursor (a cell that is diploid but will go on to make gametes). If the S phase were skipped, which meiotic division (meiosis I or meiosis II) would no longer be required?arrow_forwardBecause of the ________ alignment of homologous chromosomes during meiosis, gametes can end up with _________ mixes of maternal and paternal chromosomes. a. unvarying; different b. unvarying; duplicate c. random; duplicate d. random; differentarrow_forwardAdams maternal and paternal chromosomes have alternate forms of a gene that influences whether a person is right-handed or left-handed. One form says right and its partner says left. Visualize one of Adams spermatogonia, in which chromosomes are being duplicated prior to meiosis. Visualize what happens to the chromosomes during anaphase I and II. (It might help to use toothpicks as models of the sister chromatids of each chromosome.) What fraction of Adam's sperm will carry the gene for right-handedness? For left-handedness?arrow_forward
- Describe why it is important that meiosis produces sex cells with half as many chromosomes as the parent cell.arrow_forwardThe process of meiosis occurs during the cell cycle production and results in four unique diploid four identical diploid cells four unique haploid cells four identical haploid cells . To maintain the correct number of chromosomes in offspring, male and female gametes contain the same number half of the number twice the number of chromosomes as somatic cells. During fertilization, gametes fuse to form a diploid haplid cell called a zygote.arrow_forwardDescribe one function, brought about by the process of meiosis thatspermatogenesis and oogenesis have in common. Please write the similarities between spermatogenesis and oogenesis in a paragraph ratherthan a table. Please discuss the process mentioning differentiation, multiplication anddivision. How many stages of meiosis do they go through. Please mention if haploid ordiploid cells are formed.arrow_forward
- What are the major differences between mitosis and meiosis? Explain this both in terms of the different steps of each event and with regards to the final products of each event. Remember to mention the events which are unique to meiosis and why they are significant.arrow_forwardExamine the diagram below and answer the following questions. a) What specific stage of meiosis is this cell in? b) Exactly how many chromosomes will be in each of the 4 resulting gametes?arrow_forwardDescribe the events taking place during meiosis? What are the different phases? What is the chromosomal content of the final product? Why must this occur to make a chromosomally viable human?arrow_forward
