What happens to the 4 cells produced in meiosis (meiosis I and meiosis II)? What happens in prophase II? What happens to the chromosome number during meiosis? What happens to the gametes if nondisjunction occurs at anaphase 2? What happens directly after anaphase?
a. Crossing over take place in prophase I but not in prophase II b. Homologous chromosomes cross over in prophase II but not in prophase I c. During prophase I the chromosomes coil up; the chromo The stages of meiosis are: a. Prophase I, Metaphase I, Anaphase I, Telophase I, ...
What phase occurs during meiosis? Like mitosis, meiosis also has distinct stages calledprophase, metaphase, anaphase, and telophase. A key difference, however, is that during meiosis, each of these phases occurs twice — once during the first round of division, called meiosis I, and again durin...
What events occur during prophase I of meiosis? What occurs during cytokinesis? a. cell growth b. DNA synthesis c. chromosomes separate d. the cell splits into 2 MITOSIS/MEIOSIS : If you started with a cell with four chromosomes, what would happen if sexual reproduction took place for four...
4. Each daughter cell is genetically different from the parent cell. 5. Crossing over does not occur. 5. Crossing over occurs during Prophase I. 6. Chromosome’s duplication is followed by single nuclear division. 6. Chromosome’s duplication is followed by two nuclear divisions.Significance...
During what stage of the cell cycle does DNA replication occur? What is the main event of interphase? What happens to the DNA (chromosomes), nuclear envelope, nucleolus, centrosomes, and spindles in the cell during the following stages of mitosis? A. Prophase B. Metaphase C. Anaphase D. ...
Synapsis occurs during prophase I of meiosis I. In addition to stabilizing the homologous chromosomes so they separate correctly, synapsis facilitates the exchange of genetic material between the chromosomes. Crossing-over occurs during synapsis. An x-shaped structure called a chiasma forms where the ...
Prophase – Chromosomes condense. Mitotic spindle forms. Metaphase – Chromosomes line up in the middle of the cell. Anaphase – Chromatids separate from one another and are pull toward opposite sides of the cell. Telophase – Division of the cell contents into two new cells occurs (cytokinesis...
Prophase 1: Prophase I in meiosis is the most complicated prophase repetition that occurs in both plant and animal cells. Metaphase 1: A kind of cell division that produces gametes, cells with half the typical number of chromosomes. Anaphase1: After prophase I, the third stage of the first ...
Mitosis occurs in somatic cells, which are all cells of the body except for germ cells that undergo meiosis. 12 What mechanisms in meiosis increase genetic variation? Crossing over (the exchange of genetic material between homologous chromosomes) and independent assortment (random distribution of chrom...
