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 |
