You are watching: Which of the following occurs during meiosis but not during mitosis?
Assume the an organism exists in which crossing over does not occur, yet that all various other processes associated with meiosis take place normally. Think about how the lack of crossing over would affect the result of meiosis.If crossing end did not occur, i beg your pardon of the following statements about meiosis would certainly be true?
The cabinet is diploid because it has two set of chromosomes.Only diploid cells contain two sets that chromosomes, one maternal and one paternal. Read around diploid cells.
Synapsis occurs.The pairing that homologous chromosomes that only occurs during prophase i of meiosis is dubbed synapsis.
If a cell has completed the first meiotic division and is just beginning meiosis II, i m sorry of the complying with is an suitable description that its contents?
The following question describes the necessary steps in meiosis explained below.1. Formation of four new nuclei, each with half the chromosomes present in the parental nucleus2. Alignment that tetrads at the metaphase plate3. Separation of sister chromatids4. Separation of the homologs; no uncoupling the the centromere5. Synapsis; chromosomes relocating to the center of the cell in pairsWhich that the measures takes ar in both mitosis and also meiosis?
If the DNA content of a diploid cabinet in the G1 phase of the cell cycle is x, climate the DNA content of the very same cell at metaphase of meiosis I would be
How many different combine of maternal and paternal chromosomes can be packaged in gametes do by an organism through a diploid variety of 8 (2n = 8)?
produces offspring genetically similar to the parentOnly one individual provides a hereditary contribution to the offspring.
Homologous chromosomes save the exact same gene loci but may have various alleles of a particular gene. Sister chromatids space identical duplicates of every other created during DNA replication.One homologous chromosome originates from the father, and the other originates from the mother. Sister chromatids are identical duplicates of each other.
The parental cell that enters meiosis is diploid, whereas the 4 daughter cell that an outcome are haploid.Which declare correctly defines how moving DNA content and ploidy levels adjust during meiosis I and also meiosis II?
DNA content is halved in both meiosis I and also meiosis II. Ploidy level transforms from diploid come haploid in meiosis I, and also remains haploid in meiosis II.During anaphase of both meiosis I and meiosis II, the DNA contents (number of duplicates of chromosomes) in a cell is halved. However, the ploidy level alters only as soon as the variety of unique chromosome to adjust in the cell changes. This occurs only in meiosis i (where separation the homologous chromosomes decreases the ploidy level from 2n to n and produces daughter cells v a single chromosome set).
The events of prophase II are essentially the same as those the mitotic prophase other than that prophase II cells space haploid.
At the finish of _____ and also cytokinesis, haploid cell contain chromosomes that each consist of two sister chromatids.
telophase IAt the finish of telophase I and also cytokinesis, there space two haploid cells with chromosomes that consist of two sister chromatids each.
anaphase IDuring anaphase ns sister chromatids stay attached at their centromeres, and also homologous chromosomes move to the contrary poles.
metaphase IIMetaphase II is basically the very same as mitotic metaphase other than that the cabinet is haploid.

During anaphase ns homologous chromosomes, consist of of sisters chromatids, move to the opposite poles.
