Directions : Determine whether the following characteristics apply to mitosis, meiosis, or both, by putting into appropriate column.1. No crossing over of chromatid arms.2. Two divisions of the nucleus.3. Four daughter cells produced.4. Associated with growth, development, and asexual reproduction.5. Associated with sexual reproduction.6. One division of the nucleus7. Two daughter cells produced.8. Involves duplication of chromosomes during interphase.9. Chromosome number remains the same.10. Chromosome number is halved.11. Crossing over between chromatid arms may occur.12. Daughter cells are identical to parent cell.13. Daughter cells are not identical to parent cell.14. Produces sex cells. (egg and sperm cells)15. Happens in plant and animal cells.16. Type of cell division.17. Parent cell has 46 chromosomes (in human)18. Daughter cell has 23 chromosomes (in human)19. Daughter cell has 46 chromosomes (in human)20. Produces body cells. (Skin, bone, nerve, etc.)

IV. Observation: No Crossing Over Crossing Over Appearance of Gamete Cells Appearance of Gamete Cells V. Analysis: 1. If the two sister chromatids are the same, how are they called? 2. Which specific parts exchanged genetic information during cross over? 3. What is crossing over? 4. When will crossing over occurs? Why? 5. What will happen after crossing over? 6. How do meiosis contributes to genetic variation, while mitosis does not? 7. Why is crossing over important for evolution of species?

Need help with three question. Multiple choise. 1.) How is the outcome of meiosis different from the outcome of mitosis? a.) The daughter cells produced in mitosis are genetically different from the parent cells, but have the same number of chromosomes, while these are genetically similar in case of meiosis and have fewer chromosomes. b.) The daughter cells produced in mitosis are genetically similar to the parent cells and have the same number of chromosomes, while these are genetically different in meiosis and have half the number of chromosomes. c.) The daughter cells produced in both cases are genetically similar to the parent cells, but in meiosis, there are fewer chromosomes. d.) The daughter cells produced in both cases are genetically different, but in mitosis, there are fewwer chromosomes in daughter cells. 2.) What would be the effect on the number of chromosomes in gametes due to non-disjunction? a.) The chromosome number of the gametes remains the same as the parent…

RNING SERVICES SQU LIBRARIES SQU PORTAL ATTENDANCE ENGLISH (EN) Answer: AMYLOSE The sperm of Panthera leo contains 19 chromosomes, which of the following is/are true about somatic cells? Select one or more: a. The Panthera leo cells normally contain 38 homologous chromosome pairs b. Panthera leo normally has 38 chromosomes in its body cells c. There are 38 sister chromatids per cell in G2 phase d. The somatic cell contains 38 sister chromatids e.
