What is the fundamental difference between mitosis and meiosis? A. DNA is replicated twice in meiosis, but only once in mitosis. B. The number of DNA molecules per cell nucleus is cut in half in meiosis but remains constant in mitosis. C. The number of chromosomes doubles in meiosis, whereas it stays the same in mitosis. D. Mitosis involves two cell divisions, whereas meiosis only involves one.
How do cells after meiosis compare with cells that are in the prophase of meiosis I?A) The cells have half the number of chromosomes and one-fourth the amount of DNA.B) The cells have the same number of chromosomes and half the amount of DNA.C) The cells have half the number of chromosomes and half the amount of DNA.D) The cells have half the amount of cytoplasm and twice the amount of DNA.
Even though the processes are very similar, mitosis and meiosis are two very distinct processes. What is the difference between meiosis and mitosis? a. Mitosis results in two identical sister cells genetically identical to the original parent cell, while meiosis also starts with diploid but results in haploid cells. b. Mitosis only occurs in plants and single cell organisms, while meiosis only occurs in animals. c. Mitosis starts with diploid but results in haploid cells, while meiosis results in two identical sister cells genetically identical to the original parent cell.
What kinds of cells would the haploid cells be if meiosis were occurring in a plant? in an animal?
Which statement below best describes the overall function of meiosis 2? A. Separates homologous chromosomes prior to cell division B. Separate sister chromatids prior to cell division C. Independently arranges homologous chromosomes
A diploid male organism has two homologous chromosomes. A and B are from its maternal parent, while A’ and B’ are from its paternal parent. Draw the chromosomes at the following stages: a, anaphase of mitosis b. anaphase of the first meiotic division c, anaphase of the second meiotic division If the same chromosomes were involved in meiosis in a female, would the kind of egg nuclei produced be different from the sperm nuclei? Why?
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.
A diploid organism has 18 chromosomes in its skin cells. Which of the following correctly describe the ploidy of this organism? Select one: a. All gametes contain nine pairs of chromosomes. b. All autosomal cells contain nine chromosomes. c. 2n = 36 and n = 18 d. 2n = 18 and n = 9
Give explanation X and Y chromosomes are not homologs, but in meiosis they do pair and segregate in XY organisms to create 50% haploid gametes with an X chromosome and 50% haploid gametes with a Y chromosome. How is pairing achieved? a. Since all other homologous chromosomes pair, the remaining two chromosomes pair by default. b Pairing proteins are capable of binding to different genes on the X and Y chromosomes, which allows them to pair. c. None of the statements is correct. d. They don't actually pair. Random segregation generally ensures the X and Y chromosomes separate. e.Pseudoautosomal regions that are homologous exist at the tips of both the X and Y chromosomes, and they allow pairing.

How do you know? b) Assuming all of the chromosomes present during Meiosis II are shown in the figure above, how many chromosomes (counting homologous pairs as two chromosomes) does a gamete from this organism have? c) Draw the same cell during the same phase of Meiosis I.
