Chapter 2, Problem 40P
Summary Introduction
To determine: The types of cell cycle occur in a fern, moss, flowering plant, pine tree, mushroom, frog, butterfly, and snail to divide and which cells divide by which cycle.
Introduction: Meiosis and mitosis are two types of cell division methods. In meiosis, the parent cell divides and gives rise to four daughter cells wherein in mitosis, the parent cell divides and gives rise to two daughter cells.

Indicate the stage of meiosis (e.g., metaphase 2 = M2; prophase 1 = P1; anaphase 2 = A2; etc.) in which each of the following events occurs.
first cell stage in which the original maternal/paternal chromatid doublets (chromosomes) are in separate cells
chromosomes (chromatid doublets) first synapse (tetrads are visible)
chromosomes (chromatid doublets, but NOT tetrads) line up in single file one doublet next to the other
crossing over and recombination occurschromatid doublets move toward opposite poles of cellchromosomes (DNA) replicatechromatids separate as centromeres dividechromosomes (chromatid doublets) line up as tetrads at the cell’s equator

- How is the outcome of meiosis different from the outcome of mitosis? The daughter cells produced in mitosis are genetically different from the parent cells, but have the same number of chromosomes, while these are genetically similar in case of meiosis and have fewer chromosomes. The daughter cells produced in mitosis are genetically similar to the parent cells and have the same number of chromosomes, while these are genetically different in meiosis and have half the number of chromosomes. The daughter cells produced in both cases are genetically similar to the parent cells, but in meiosis, there are fewer chromosomes. The daughter cells produced in both cases are genetically different, but in mitosis, there are fewwer chromosomes in daughter cells.arrow_forwardWhat are some of the key differences between mitosis and meiosis? Select all that apply. Reduction division occurs in meiosis only. Mitosis produces four daughter cells and meiosis only produces two. Gametogensis occurs in mitosis only. Meiosis produces four daughter cells and mitosis only produces two. Mitosis produces cells that are genetically identical to the parent cell whereas meiosis produces cells that only have half the genetic material of the parents. Both Mitosis and meiosis produce cells that are genetically identical to the parent cell.arrow_forwardDraw the distribution of DNA (one set of homologous chromosomes) during meiosis.
