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 in daughter cells are produced in meiosis?
Now there are two daughter cells, each with 23 chromosomes (23 pairs of chromatids). In each of the two daughter cells the chromosomes condense again into visible X-shaped structures that can be easily seen under a microscope.
Does mitosis produce 2 or 4 daughter cells?
Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells.
Does mitosis daughter cells have 46 chromosomes?
Explanation: If a human cell undergoes mitosis its daughter cells will have 46. … There is no change in chromosome number in mitosis.
What type of cells does meiosis produce?
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction.
Where does mitosis occur in the body?
Cell division by mitosis occurs in all human body cells except the gonads (sex cells). During mitosis, the DNA is exactly copied and a new daughter cell created with the same number of chromosomes as the parent cell, ie 46.
Why the chromosome number has reduced to half in daughter cells in meiosis?
The reduction of chromosome number in meiosis is a central event in the lives of most eukaryotes, including humans. It makes diploidy possible because the gametes that are produced with half the chromosome number of their parent cells can then fuse to form a diploid zygote.
How does mitosis maintain 46 chromosomes in daughter cells?
Mitosis is a fundamental process for life. During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells. … When the sperm and egg cells unite at conception, each contributes 23 chromosomes so the resulting embryo will have the usual 46.
How many chromosomes do daughter cells have after meiosis 1?
By the end of meiosis, the resulting reproductive cells, or gametes, each have 23 genetically unique chromosomes. The overall process of meiosis produces four daughter cells from one single parent cell. Each daughter cell is haploid, because it has half the number of chromosomes as the original parent cell.
