Sexual and Asexual Reproduction w/ Mitosis and Meiosis
| Question | Answer |
|---|---|
| New Cell | Daughter Cell |
| Results in new offsprings from the union of 2 parents-Has variation. | Sexual Reproduction |
| Is one-half of two identical copies of a replicated chromosome. | Chromatids |
| Body Cells | Somatic |
| Sex Cells | Gametes |
| Original Cell | Parent Cell |
| Total number of required chromosomes; 46 chromosomes(2n) =46 chromosomes. | Diploid |
| 1/2 the required number of chromosomes; 23 chromosomes(n)-Haploid | Haploid |
| Preparation and growth of DNA; no cell division; DNA Replication occurs during this time. | Interphase |
| Located in nucleus; contains heredity information. | Chromosomes |
| Asexual cell division; occurs in somatic(body) cells. | Mitosis |
| Sexual cell division; occurs in gametes (sperm,egg). | Meiosis |
| Male gametes; 4 produced each time sex cell divides. | Sperm |
| Female gametes; 4 produced each time sex cell divides. | Egg |
| Cell Division; Prophase, Metaphase, Anaphase, Telophase. | PMAT |
| Final step in cell division where cell splits into 2 completely equal parts | Cytokinesis |
| Occurs when a cell loses its ability to control cell division. | Cancer |
| Exchange of genetic material during meiosis, causes genetic variation among sex cells(gametes). | Crossing Over |
| Failure of homologous chromosomes to separate properly resulting in an unequal number of chromosomes in each cell. Cause of DOWN SYNDROME (TRISONOMY 21). | Nondisjunction |
| Results in two offsprings from one parent-NO variation. | Asexual Reproduction |
| Holds the chromatids together at the center of the chromosomes. | Centromere |
| Differences in cells. | Variations |
