- Here is a list of events out of order for nondisjunction during meiosis l: A One homologous chromosome pair moves to the same side of the cell B Gametes are produced with the wrong number of chromosomes C Alignment of homologous pairs on the metaphase plate D Pairing and synapsis of homologous chromosomes E Spindle fibers shorten to separate the homologous chromosomes What is the correct order of events? i DCEAB CDAEB CDAEA DCEBAarrow_forwardWhich of the following occur during Meiosis I? Select all that apply Spindle tension aligns the chromosomes in the center of the cell Homologous chromosomes align in the center of the cell Ploidy is changed from diploid to haploid Sister chromatids are separatedarrow_forwardFor this DTL, you will compare key stages of mitosis and meiosis. Not all stages are shown. Use the template attached HERE which starts with a "parent" cell that is 2n=4. Use / for unreplicated chromosomes and X for replicated chromosomes. Make sure nonhomologs are different sizes. Put alleles A and a on the large pair of homologs and alleles B and b on the small pair of homologs. (Put these letters by the little mark on each chromosome. Each letter represents one of a thousand genes along that chromosome.) Use a metaphase plate that is vertical. Do not indicate the nuclear membrane, spindles or that the chromosomes are decondensed (unwound) in interphase. For each cell, label # n (ploidy #, haploid or diploid)=______ (#chromosomes) and amount for DNA versus a gamete which is 1x.arrow_forward
- Assume that cell does mitosis Assume that cell does meiosis What is the diploid number of chromosomes in this organism? Give the number of chromosomes and the number of DNA molecules per cell present at the stages represented. I tried to solve them, but I'm not sure what I did right and what was wrong. Please correct it for me. See that attached photo.arrow_forwardbelow you will sketch the difference between cells that go through mitosis versus meiosis. the focus is on the number of chromosomes, not the specific steps, so you only need to draw the chromosomes in each circle. do this drawing for a fruit cell, whose body cells have 8 chromosomes or 4 homologous pairs.
