  5. Meiosis results in 4 ________ . Diploid Cells Haploid Cells

  6. This is the exchange of genetics information between homologous chromosomes Crossing Over Divisions

  7. Crossing over takes place during this part of Meiosis Meiosis I Meiosis II

  8. Gametes are ________ to help organisms maintain a constant chromosome number Diploid Haploid

  9. How many times does cytokinesis occur during the whole process of meiosis? 1 2

  10. After meiosis, how does the # of chromosomes in the cells compare to the parent cell? Same Different

  11. One chromosome of a matched pair is called a _______. Sister chromatid Homolog

  12. Two chromosomes that are alike in shape, size, etc… Homologous Pairs Sister chromatids

  13. What is a the term for a fertilized egg? Byah Zygote

  14. If a cell has 18 chromosomes before mitosis, how many chromosomes will each daughter cell have? 18 9

  15. What are chromosomes made of? DNA RNA

  16. Homologous pairs of chromosomes are found in these cells Haploid – 1n Diploid – 2n

  17. If the haploid # of a cell is 4, how many chromosomes are found in the organisms body cells? 8 4

  18. How many chromosomes are found in human sperm & egg cells? 23 46

  19. Gametes are made by this process? Meiosis Mitosis

  20. Which cell is an example of a haploid cell? Muscle cell Sperm cell

  21. Sister chromatids separate at this phase… Anaphase I Anaphase II

  22. How many egg cells are made through meiosis? 4 1

  23. These cells are formed by meiosis in females that are broken down Polar bodies Eggs

  24. The exchange of corresponding DNA segments is called Crossing over Fertilization

  25. This type of reproduction is the reason we need meiosis to take place Asexual Reproduction Sexual Reproduction

  26. Which human cells have 23 chromosomes each? Eggs & Sperm Muscle cells and Nerve Cells

  27. Cytokinesis occurs during metaphase II True False

  28. Homologous pairs are alike in shape and size True False

  29. Meiosis produces four nuclei that have a different chromosome number from the original cell’s nucleus True False

  30. Gametes are diploid so that when fertilization occurs, the resulting offspring will have the same number of chromosomes as the parent True False

  31. Crossing over takes place between homologous chromosomes True False

  32. Polar bodies are created in females during meiosis True False

  33. Normal human body cells contain 48 chromosomes True False

  35. Haploid number is 4…Diploid number is _____. 4 8

  36. Coiled up strands of DNA are called…. Narsnoctocows Chromosomes

  37. Zygotes are another name for…. Fertilized eggs Space aliens

  38. 1n = Haploid Diploid

  39. Stage that cells spend most of their life in Interphase Prophase

  40. Which is an example of an somatic cell? Nerve Cell Sperm Cell

  42. Sister Chromatids pull apart during Anaphase II Prophase II

  43. Diversity and variation is possible because of….. Asexual reproduction Sexual Reproduction

  44. Mitosis reduces the number of chromosomes in a cell True False
