| Question | Answer |
|---|---|
| Mitotic division | The normal process that body cells use to grow new tissue or repair existing tissue. |
| How do cells divide during mitosis? | Cell divide to form two daughter cells that are identical to the parent cell |
| In mitosis the number of chromosomes... | Stay the same as in the parent cell |
| What are the phases in mitosis? | Interphase, prophase, metaphase, anaphase, and telphase |
| Meiotic division | The process through which gametes or spores are produced. |
| In what cells does meiotic division only occurs in? | Eukaryotic cells |
| In meiotic division, a form of cell division occurs that... | Produces haploid daughter cells with half of the species' usual number of chromosomes. |
| Gametes | The resulting daughter cells of Meiotic division |
| What are the phases in meiosis? | Prophase 1, metaphase 1, anaphase1, telophase 1, prophase 2, mataphase 2, anaphase 2, and telophase 2. |
| Meiosis produces _______ daughter cells that are genetically ________. | Four; diverse |
| What are the two gamete cells? | Sperm or egg |
| What will happen if a gamete cell is able to unite with the opposite type or gamete cell? | The chromosomes will combine to yield the full number of chromosome pairs, and normal mitotic cell division can begin. |
| Does crossing over occur during meiosis or mitosis? | Meiosis |
| Crossing over | When two chromosomes pair up and exchange parts of their DNA. |
| What phase does crossing over occur in? | Prophase 1 |
| What does crossing over provide? | It provides genetic diversity between the parents and their offspring. |
| Genetic variation | Occurs when alleles are randomly sorted during meiosis. |
| Mutations | Can occur whenever a segment of DNA is inserted, deleted, or substituted. |
| Mutations sometimes create changes in an organism's __________ or the _________ or it's potential offspring. | Phenotype; phenotype |
| Can mutations sometimes have no effect on an organism at all? | Yes |
| Mutation that have no effect on an organism are called... | Silent mutations |
| How can mutations only be passed down to an organism's offspring? | Only if the mutation occurs in the sex cells, or gametes, or the organism. |
| Mutations in somatic cells _______ affect the genotype of potential offspring. | Don't |
| Mutations ___________ genetic variability because they _________ the genotype of an organism. | Increase; change |
