7.3 The Human Life Cycle
Across
- 4. meiosis in males which produces sperm.
- 5. a type of cell division that produces exact copies of the parent cell (2n). Occurs after a zygote forms.
- 10. I, phase in which synapsis and crossing over occur.
- 12. a 2n=28 individual undergoes meiosis. How many chromosomes will each daughter cell have after meiosis II?
- 13. chromosomes that have the same shape and size; "look alike chromosomes".
- 14. a type of cell division that reduces the chromosomal number in half to produce gametes.
Down
- 1. a brief period of time that occurs between meiosis I and meiosis II.
- 2. meiosis in females which produces eggs.
- 3. the organ in males that produces gametes.
- 5. I, homologue pairs align at the equator during this phase.
- 6. a pair of homologues
- 7. chromosomal state of zygote, parent cells, and individuals.
- 8. process by which homologues pair up; "snap" together.
- 9. the first cell formed after fertilization.
- 11. chromosomal state of gametes such as egg and sperm.
