1. Most cells in the body of a grasshopper have 22 chromosomes. In some cells 11 chromosomes are found. What process produced those cells? | Meiosis or Meiotic
|
2. Where are egg cells formed and where are sperm cells formed? | ovary AND Testis
| 3. What type of cell division produces haploid (1/2 of the chromosomes) cells? | Meiosis or Meiotic
| 4. Give one important difference (other than the number of parents) between sexual and asexual reproduction. | sexual reproduction more genetic variation
| 5. Fusion of male and female gametes is called: | fertilization
