Name _________________________________________ ! ! ! ! ! Meiosis Study Guide Key.! Use the words in the box to answer the questions below. Use each answer once! Egg Meiosis Female Mitosis Full Set Sperm Half Set X Male Y 1. The female sex cell is the Egg.! ! ! 2. The male sex cell is the Sperm.! ! ! ! 3. Mitosis is the replication of body cells that allows the two new cells to have ! ! a Full Set of chromosomes.! ! ! ! 4. Meiosis is the replication of sex cells that allows the four new cells to have a ! ! Half set of chromosomes.! ! ! 5. An egg carries the sex chromosome X, if it is fertilized by a homozygous sperm! ! the gender of the offspring will be Female.! ! ! ! 6. An egg that is fertilized by a heterozygous sperm carrying the Y chromosome will ! ! produce an offspring with the gender Male.! ! ! 7- 12 List three pros and cons for asexual reproduction.! ! Asexual Reproduction Pro’s! ! ! Asexual reproduction con’s ! ! 7. Needs only one parent.! ! ! ! 10. Less likely to produce a new species. ! ! ! 8. High Success rate.!`! ! ! ! 11. Lower genetic variety! ! ! 9. Requires less energy.! ! ! ! ! ! ! ! ! ! ! ! 12. more susceptible to diseases and bad ! qualities! Name _________________________________________ ! ! 13- 18 List three pros and cons for Sexual reproduction.! ! Sexual Reproduction Pro’s! ! ! Sexual reproduction con’s ! ! 13. Creates a new organism with new traits! ! 16. Requires a lot of energy ! ! ! 14. more disease resistant! `! ! ! 17. lower chance of fertilization! ! ! 15. more likely to adapt.! ! ! ! 18. only females capable of gestation! ! ! ! 19. Show a Punnett square that demonstrates the probability of having a male and female child exclude environmental factors and be sure to use the alleles for sex chromosomes.! ! ! ! ! ! X! ! Y! ! X! ! ! XX! ! XY! ! XX! ! XY! ! ! ! ! X! ! 20. If a dog’s body cell has 78 chromosomes, how many chromosomes does a dog’s sex cell have?! ! A Dog’s sex cell has 39 chromosomes.! ! ! ! 21. Why is it important that meiosis creates cells with half the number of chromosomes?! ! It is important for the cells to have half the number of chromosomes so they can get traits from both parents.! ! ! 22. What is the purpose for sexual and asexual reproduction? ! To ensure the survival of the species by creating new offspring.! ! ! Name _________________________________________ ! ! 23-26 provide two similarities and two differences for meiosis and mitosis.! ! Similarities! ! ! ! ! ! Differences! ! 23. Both Create new cells! ! ! ! ! ! ! ! ! ! ! ! ! 24. The sequence of stages and phases. ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! 25. Meiosis results in 4 sex cells, Mitosis 2 ! body cells! 26. Meiosis result in half the number of ! chromosomes, Mitosis results in a full ! set of chromosomes!
