During this phase of meiosis, the nuclear envelope shown in white in the diagram at right breaks up and disappears. In general, mitosis division of the nucleus is preceded by the S stage of interphase during which the DNA is replicated and is often accompanied or followed by cytokinesis, which divides the cytoplasm, organelles and cell membrane into two new cells containing.
During meiosis and cytokinesis, one diploid cell will divide into 4 genetically unique haploid daughter cells or gametes.
The cell membrane starts pinching inward to form two separate cells. Archived from the original PDF on 11 December Retrieved 9 September Other examples are potato and banana. Archived from the original on 23 October
Modeling Meiosis!!! Should nondisjunction occur during meiosis, the resulting egg or sperm cell will have an incorrect number of chromosomes; if this sex cell is then fertilized, the fetus will have a chromosomal abnormality. Humane Society of the United States.
It is the reproduction method used by plants , fungi , and bacteria , and is also the way that clonal colonies reproduce themselves. However in Metaphase I, the chromosomes line up in homologous pairs, not along the metaphase plate but across from a chromosome carrying a similar trait.
Grafting can be regarded as cloning, since all the shoots and branches coming from the graft are genetically a clone of a single individual, but this particular kind of cloning has not come under ethical scrutiny and is generally treated as an entirely different kind of operation.
