Is cell division the same in all cells?
Depending on the type of cell, there are two ways cells divide—mitosis and meiosis. Each of these methods of cell division has special characteristics. One of the key differences in mitosis is a single cell divides into two cells that are replicas of each other and have the same number of chromosomes.
Is meiosis genetically identical or different?
The nuclei resulting from meiosis are never genetically identical, and they contain one chromosome set only—this is half the number of the original cell, which was diploid. The differences in the outcomes of meiosis and mitosis occur because of differences in the behavior of the chromosomes during each process.
How does mitosis ensure that daughter cells are identical?
During mitosis, all chromosomes separate into chromatids (the two halves of a chromosome). … Thus, mitosis uses chromosome replication to produce two identical diploid daughter cells, which are genetically identical to the diploid parent cell. This way all your cells have identical DNA composition.
Are daughter cells are genetically identical to each other?
Daughter cells are genetically identical with each cell and with the parent cell. Daughter cells are genetically different with each cell and with the parent cell. May occur in all parts of the body. Meiotic division is restricted to the gonads.
Which are main types of cell division What are the differences?
(i) The two main types of cell division are ‘mitosis ‘ and ‘meiosis’ . (ii) Mitosis occurs in the somatic cells and stem cells of the body , whereas meiosis occurs in germ cells. (iii) In mitosis , the chromosome number remains the same and two daughter cells are obtained from one cell.
