Is crossing over unique to meiosis?
Yes. Crossover only occurs in prophase of meiosis I. Becuase it does not occur in mitosis, all the cells in our body are supposed to have the same genetic information (of course, excluding the cases where somatic mutations occur, such as in cancer).
What two factors introduce genetic variation during the process of meiosis?
The two factors that introduce genetic variation during the process of meiosis are independent assortment and chromosomal crossover. These occur during prophase 1 and anaphase 1 of meiosis.
Meiosis divides the chromosomes in the nucleus how many times?
Two successive nuclear divisions occur, Meiosis I (Reduction) and Meiosis II (Division)
Why are there two sets of phases during meiosis but only one during meiosis?

How are mitosis and meiosis simlair?
Meiosis and Mitosis are both the division of something. Meiosis is the division of chromosomes and Mitosis is the division of cells. They both occur in the cell cycle. Meiosis creates 4 daughter cells and Mitosis creates two complete cells.
Which does not occur during meiosis?
two diploid daughter cells occur
How many divisions in meiosis?
Two successive nuclear divisions occur, Meiosis I (Reduction) and Meiosis II (Division)
Where is the human body does meiosis occur?
in cells. cells undergo meiosis to make sex cells. one cell splits into two cells, ad then the two cells split into two more cells.
Is crossing over unique to meiosis?

How many divisions occur in meiosis?
Meiosis does in fact divide twice, once in meiosis I (cytokinesis) and meiosis II (cytokinesis) basically it divides into four daughter cells at the end of meiosis. Two from meiosis I and four in meiosis II
What parts of your body does meiosis occur?
it occurs in the gametes, the sex cells. where mitosis occurs in all other cells that have two halves of chromosomes, meiosis occurs in cells which only have one half of the chromosomes.
Can mitosis and meiosis occur at the same time?
No,Meiosis is done in the gonads to produce gametes and it produce 4 haploid cells while mitosis happens ia all body cells producing two daughter cells diploid similar to the parent cell
What two factors introduce genetic variation during the process of meiosis?
The two factors that introduce genetic variation during the process of meiosis are independent assortment and chromosomal crossover. These occur during prophase 1 and anaphase 1 of meiosis.
How many pairs of the nucleus occur in meiosis?
in meiosis, two new haploid sex cells are "born" by the division of two other haploid sex cells. So, at the end, there are 4 nuclei.
Meiosis divides the chromosomes in the nucleus how many times?
Two successive nuclear divisions occur, Meiosis I (Reduction) and Meiosis II (Division)
Why are there two sets of phases during meiosis but only one during meiosis?
burr
What happens during the cytokines phase of meiosis?
The two complete daughter cell form.
