Does crossing over take place during mitosis or meiosis why?

For the most part, meiosis and mitosis are similar. Both processes produce genetically distinct daughter cells. However, a major difference exists in the way they handle the chromosomes. During meiosis, each chromosome pair splits and produces two daughter cells. One daughter cell receives two copies of one chromosome and one daughter cell receives none. This process results in half as many chromosomes in each daughter cell as the original cell.

Does mitosis have crossing overs?

The answer is no, meiosis does not have crossover. After the first division, the chromosomes separate to form two new daughter cells. The two daughter cells each end up with one copy of each chromosome. Crossover does not occur during the division process; rather, crossover happens after the division is completed.

Does meiosis have crossing overs?

No meiosis has crossing over. During meiosis I, two of the chromosomes from each parent pair make a single copy of itself, and then two from that copy pair with each other in a process called recombination. This helps ensure that the child has a unique combination of genes from both parents. In the second meiosis, those pairs of chromosomes again line up to form two new pairs.

Does mitosis have a crossing over?

When you look at your cells under a microscope, you can easily see two pairs of chromosomes in each cell -- one pair from each parent. In most species, the chromosome pairs are held together by a piece of protein called a centromere. The centromeres of each pair line up with one another and line up with the middle of the cell. When the cell divides, each of the daughter cells receives one pair of chromosomes, as do the grandchildren, great-grandchildren, and so on

Does meiosis have crossing gaps?

There have been studies showing that the chromosome pairs in meiosis are held together by crossover proteins which can prevent the chromosomes from separating prematurely. However, it is not clear if this is the case in all species, including humans. In addition, a crossover does not guarantee the production of an equal amount of genetic information in the two daughter cells. It is likely that the chromosome pairs that have the highest probability of crossover are the ones that are most important for successful reproduction.
