|---|---|
| 1.Mitotic division | is the normal process that body cells use to grow new tissue or repair existing tissue. |
| 2.form two daughter cells that are identical to the parent cell | During mitosis, cells divide to form two daughter cells that are identical to the parent cell and to each other. |
| 3.number of chromosomes remains the same | So, in this type of cell division, the number of chromosomes remains the same as in the parent cell. |
| 4.Mitosis produces two daughter cells that are identical to | each other and to the parent cells. |
| 5.Meiotic division | Meiotic division, which only occurs in Eucharistic cells, is the process through which gametes or spores are produced. |
| 7.produces haploid daughter cells with half of the species' usual number of chromosomes. | In meiotic division, a form of cell division occurs that produces haploid daughter cells with half of the species' usual number of chromosomes. |
| 8.gametes | These resulting daughter cells are called gametes, and they aid organisms in their sexual reproduction |
| 9.crossing over | During meiosis, crossing over—a process unique to meiosis—can occur |
| 10.exchange parts of their DNA. | Crossing over occurs during pro phase I when two chromosomes pair up and exchange parts of their DNA |
| 11.Crossing over provides genetic diversity between the | Crossing over provides genetic diversity between the parents and their offspring. |
| 12.Genetic variation | Genetic variation can also occur when alleles are randomly sorted during meiosis. |
| 13.Since each offspring receives a different combination of alleles from the | Since each offspring receives a different combination of alleles from the parent organisms, phenotype diversity results. |
| 14.Mutations | Mutations in genes can occur whenever a segment of DNA is inserted, deleted, or substituted. |
| 15.segment of DNA is inserted, | Mutations in genes can occur whenever a segment of DNA is inserted, deleted, or substituted |
| 16.Mutations sometimes create changes in an | Mutations sometimes create changes in an organism's phenotype or the phenotype of its potential offspring, but they also can have no effect on an organism at all. |
| 17.silent mutations. | Mutations that have no effect on an organism are called silent mutations |
| 18.Mutations will only be passed on | Mutations will only be passed on to an organism's offspring in the mutation occurs in the sex cells, or gametes, of the organism. |
| 19.Mutations in somatic cells do not | Mutations in somatic cells do not affect the genotype of potential offspring |
| 20.Mutations increase genetic variability because | Mutations increase genetic variability because they change the genotype of an organism. |
