(b) Metaphase of mitosis and metaphase II of meiosis
(c) Metaphase I and metaphase II of meiosis
(d) Telophase of mitosis and telophase II of meiosis
(e) Pachytene and diplotene stages of meiotic prophase I

- Even experts make mistakes. Please point out the biggest mistake in the illustration below including the figure legend written by a sperm sorting guru and renowned scientist. How do you correct it?arrow_forwardMODIFIED TRUE OR FALSE. In the following items, read each statement carefully. I. Mitosis and meiosis are two cellular process that might be quite similar in terms of stages, but technically, different process that have two different functions. II. As an example, mitosis involves the production of genetically different daughter cells whereas meiosis involves the production of genetically identical daughter cells. a. The first statement (I) is correct and the second statement (II) is wrong b. The first statement (I) is wrong and the second statement (II) is correct c. Both statements are correct d. Both statements are wrong I. The continuity of life from one cell to another has its foundation in the reproduction of cells by way of the cell cycle.II. The cell cycle is an orderly sequence of events in the life of a cell from the division of a single parent cell to produce two new daughter cells and are highly conserved across eukaryotes.…arrow_forwardPlese help.

- True or False. 1. a.) A diploid organism with 2N=8 would have 4 chromosomes in each gamete. b.) Homologous chromosomes do not pair up during asexual cell division. c.) Gametes have the same number of chromosomes as a somatic cell. d.) Cell division would not be possible without the work of DNA Polymerase. Pick one of the FALSE statements from the 4 previous questions and explain why it is incorrect.arrow_forwardCan you help?arrow_forwardExplain well. Not put answer.arrow_forward

- Let’s model mitosis. Focus on drawing the cell nucleus taking care to model the number and location of chromosomes. Although the chromosomes are only visible in each stage, draw them in all stages for clarity sake. Draw a 2n=4 cell at G1 of interphase. Draw the same cell at the start of prophase. Draw the same cell at metaphase. Draw the cell(s) that result at the end of cytokinesis. You can draw this out on paperarrow_forwardmultiple choice.arrow_forwardFill in the red numbers.arrow_forward
