Across
- 2. Makes 4 haploid gamete cells from a diploid cell
- 6. Same as telophase 1, but a cleavage forms and two diploid cells have divided into 4 haploid cells.
- 9. No replication of DNA is required
- 10. DNA turns into visible chromosomes and the nuclear membrane dissolves
- 11. Nuclear membrane form saround the separate chromosomes and unwind
- 12. Cell only containing a single set of chromosomes and genes
- 13. Homologous chromosomes join up and share genetic onformation
- 14. DNA is in its chromatin form and replicates
- 15. Reproduction in which 2 haploid gametes unite to form a cell for a living organism
- 17. Two cells form
- 18. Same as metaphase 1
- 19. A sperm and an egg join during reproduction to produce a diploid
Down
- 1. 2 complete sets of chromosomes, one from each parent
- 3. any cell of a living organism, not reproductive cells
- 4. A diploid cell resulting from two haploid gametes
- 5. matching chromosomes from mother and father
- 7. spindle fibers pull on the chromosomes
- 8. spindle fibers form and attach to the centromeres of the homologous chromosomes
- 16. Spindles pull the sister chromatids apart and each goes towards a different pole again
