In what two ways does meiosis provide genetic variation?
The two sources of genetic variation in a cell during Meiosis are crossing-over during synapse and independent assortment.
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 happens in meiosis you that does not occur in meiosis?
One thing that happens in meiosis that does not occur in meiosis is that produces 2 cellular divisions. This occurs as a direct result of sexual reproduction.
What happens in meiosis I that does that occur in meiosis Ii?
DNA is copied.
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.
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)

When does duplication of chromosomes occur?
when does the duplication of chromosomes occur?

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 happens in meiosis you that does not occur in meiosis?
One thing that happens in meiosis that does not occur in meiosis is that produces 2 cellular divisions. This occurs as a direct result of sexual reproduction.
In what structure does meiosis occur in bryophytes?
Meiosis occurs in the sporophyte.
What occurs in meiosis i that does not occur in meiosis ii?
DNA is copied.
