What happens to chromosomes after mitosis and meiosis?
At the end of mitosis, the two daughter cells will be exact copies of the original cell. Each daughter cell will have 30 chromosomes. At the end of meiosis II, each cell (i.e., gamete) would have half the original number of chromosomes, that is, 15 chromosomes.
Is there a change in chromosome number during mitosis?
So during a mitotic cell cycle, the DNA content per chromosome doubles during S phase (each chromosome starts as one chromatid, then becomes a pair of identical sister chromatids during S phase), but the chromosome number stays the same.
Does chromosome number change during meiosis?
During meiosis, cell division makes the number of chromosomes get reduced to only a half of the original. Four new daughter haploid cells are produced from the original cell, and each have distinct genes from the parent cell.
What is the end result of mitosis?
Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells.
What is the end result of meiosis?
What is the end result of meiosis? Results in four daughter cells, not genetically identical but contains same number of chromosomes.
Does chromosome number change in mitosis and meiosis?
Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. In contrast, meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell.
How many chromosomes are in each stage of mitosis?
Once mitosis is complete, the cell has two groups of 46 chromosomes, each enclosed with their own nuclear membrane. The cell then splits in two by a process called cytokinesis, creating two clones of the original cell, each with 46 monovalent chromosomes.
