mitosis meiosis
| Term | Definition |
|---|---|
| mitosis | a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth. |
| diploid (number) | containing two complete sets of chromosomes, one from each parent. |
| Interphase | the resting phase between successive mitotic divisions of a cell, or between the first and second divisions of meiosis. |
| crossing over | the exchange of genes between homologous chromosomes, resulting in a mixture of parental characteristics in offspring. |
| anaphase | the stage of meiotic or mitotic cell division in which the chromosomes move away from one another to opposite poles of the spindle. |
| haploid/Monoploid | haploid number for humans (half of 46) is 23; and the monoploid number equals 46 divided by the ploidy level of 2, which is also 23. |
| daughter nuclei | The original nucleus is called the parent nucleus, and the nucleus remaining after the decay |
| Tetrad | a group or set of four. |
| gametogenesis | the process in which cells undergo meiosis to form gametes. |
| meiosis | a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores. |
| metaphase | the second stage of cell division, between prophase and anaphase, during which the chromosomes become attached to the spindle fibers. |
| cytokinesis | the cytoplasmic division of a cell at the end of mitosis or meiosis, bringing about the separation into two daughter cells. |
| disjunction | a lack of correspondence or consistency. |
| variation | a change or difference in condition, amount, or level, typically with certain limits. |
| telophase | the final phase of cell division, between anaphase and interphase, in which the chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed. |
| replication | the action of copying or reproducing something. |
| synapsis | the fusion of chromosome pairs at the start of meiosis. |
| prophase | the first stage of cell division, before metaphase, during which the chromosomes become visible as paired chromatids and the nuclear envelope disappears. The first prophase of meiosis includes the reduction division. |
| centrioles | a minute cylindrical organelle near the nucleus in animal cells, occurring in pairs and involved in the development of spindle fibers in cell division. |
