What two things happen during meiosis?
chromosomes split and the cell divides The above mentioned two things happen in mitosis also, so the correct answer would be - 1. Exchange of chromatin material by crossing over and 2. Reduction in the number of chromosomes to half.
How is forming tetrads in prophase 1 different from mitosis?
Tetrads don't form in mitosis. Tetrads form so that chromosomes can undergo crossing over which is a form of genetic recombination. The products of meiosis are gametes which ensure genetic diversity in subsequent generations. In mitosis, the daughter cells are genetically identical to the parent cell. No genetic recombination occurs in mitosis.
What is the exchange of a corresponding segment between homologous chromosomes?
It would appear you are speaking of crossing over which takes place in Prophase I of meiosis.
How many times does mitosis happen in a day?
10000000 time in 1 sec son
What phase does meiosis crossing over occur?
prophase 1.
What happens during prophase you that does not happen during mitosis?
Prophase is one of the stages in the process of mitosis, the stages of mistosis are : 1. Prophase 2. Metaphase 3. Anaphase 4. Telophase. So metaphase, anaphase, and telophase are what happends in mitosis and does not happen in prophase. And what happens in prophase that does not in mitosis is that the sister chromatids that were formed during interphase have shortened and thickened and are now visible with a light microscope.

Why does crossing-over not occur in mitosis?
well from what i understand mitosis is just the replication of a cell, a cell divides into two cells and it is not being effected by any other cell so crossing over cant occur Crossing over occurs in meiosis to create diversity in the genetic material so the offspring is neither identical to father or mother. in mitosis it does not occur because the parent cell is making an identical copy of itself, so the DNA does not need to vary.

What effect does crossing over in propahse 1 have on the cells?
Crossing over creates a genetic recombination of the DNA.
Differences between mitosis and meiosis?
place of occurence ;mitosis= somatic cells | meiosis=gonadic cells crossing over;mitosis=does not occur | meiosis=occur during prophase of meiosis 1 to form tetrads number of daughter cell;mitosis=two | meiosis= four genetic variation;mitosis=no variation produced| meiosis=produces genetic variation genetic composition in daughter cell; mitosis=identical to the parent cell | meiosis= non identical to the parent cell and each other
How many times does mitosis happen in a day?
10000000 time in 1 sec son
What is the longest stage of meiosis?
It is prophase because it is where chiasmata is formed and crossing over between non sister chromatids of homologous chromosomes happen. it is further divided into 1.diplotene2.zygotene3.pachytene4.leptotene and5.diakinesis stages
What are the release dates for Birnkrant 616 - 2006 Crossing Over Part 1 1-2?
Birnkrant 616 - 2006 Crossing Over Part 1 1-2 was released on: USA: January 2006
What results from th eprocess of crossing-over during prophase 1?
During the crossing-over of pro phase 1, chromosomes of a homologous pair break and exchange genes.
What phase does meiosis crossing over occur?
prophase 1.
