In prophase I the homologous chromosomes pair and form tetrads, during which crossing over occurs and genetic material is exchanged between the homologous chromosomes.

During which phase of meiosis do tetrads line up in the middle of the cell?
Tetrads line up in the middle of the cell during metaphase I.
When does crossing over happen in mitosis 1?
Mitosis does its crossing over in prophase
What are the five stages of cell division?
1. Interphase 2. Prophase 1 3. Metaphase 1 4. Anaphase 1 5. Telophase 1 and Cytokiesis 6. Prophase 2 7. Metaphase 2 8. Anaphase 2 9. Telophase 2 and Cytokiesis
What order does the cell cycle happen?
1. Interphase 2. Prophase 3. Metaphase 4. Anaphase 5. Telophase 6. Cell division (cytokinesis in animal cells and cell wall formation in plant cells) Note that 2, 3, 4 and 5 together form nuclear division.
What are the two main phases of cell division in order?
Are you talking about Meiosis 1 and meiosis 2? If you are the steps are Interphase, prophase 1, metaphase 1, anaphase 1, telophase 1/cytokinesis, prophase 2, metaphase 2, anaphase 2, and telophase 2/cytokinesis
During which phase of meiosis do tetrads line up in the middle of the cell?
Tetrads line up in the middle of the cell during metaphase I.
Number of cells during prophase?
There is still only 1 cell during prophase.
How many chromosomes does a sperm cell have at prophase I?
Sperm are all 1N (half the complement of chromosomes of the original male). Prophase 1 in meiosis the cell is 4N Prophase 2 in meiosis the cells are 2N Final division creates 1N cells.
If a cell has a diploid number of 32 what would be the chromosome number of a cell in late prophase 1 of meiosis?
32
How many cell division in mitosis in mitosis?
1 splits in two
When does crossing over happen in mitosis 1?
Mitosis does its crossing over in prophase
What are the five stages of cell division?
1. Interphase 2. Prophase 1 3. Metaphase 1 4. Anaphase 1 5. Telophase 1 and Cytokiesis 6. Prophase 2 7. Metaphase 2 8. Anaphase 2 9. Telophase 2 and Cytokiesis
What happens to homologous chromosomes during prophase 1 of meiosis which does not occur during prophase of mitosis?
In mitosis each daughter cell ends up with the same number of chromosomes as the mother cell.
The longest phase of the cell cycle is what?
Interphase - which includes the G1, S and G2 phases.
What would happen if homologous chromosomes did not pair in prophase 1?
if homologous chromosomes didn't pair up in Prophase 1 the DNA between the parents isn't distributed equally to the offspring, or variation would not occur.
What order does the cell cycle happen?
1. Interphase 2. Prophase 3. Metaphase 4. Anaphase 5. Telophase 6. Cell division (cytokinesis in animal cells and cell wall formation in plant cells) Note that 2, 3, 4 and 5 together form nuclear division.
When in the cell cycle does the nuclear membrane begin to fade?
In mitosis the nuclear envelope begins to break in prophase. In meiosis the nuclear envelope begins to break in prophase 1.
