- 3. Exchange of genetic material between non-sister chromatids of homologous chromosomes during meiosis
- 7. Chromosomes that carry the same type of genetic information (genes) in the same location are called....
- 9. Process by which haploid eggs are create
- 11. Two homologous chromosomes that have been connected via synapsis
- 15. Two halves of a replicated chromosome (both halves are identical to each other)
- 16. Number of chromosomes a haploid human cell has.
- 17. Reproductive cell that is haploid (ex: sperm or egg)
- 18. Type of syndrome that is caused by trisomy 21.
- 20. Presence of different forms of the same genes/traits within a species
- 21. Process used to create gametes. Produces 4 genetically DIFFERENT gamete cells.
Down
- 1. Cells with one set of chromosomes- from ONE person. Represented by "n".
- 2. Number of chromosomes a diploid human cell has.
- 4. Process by which haploid sperm are created.
- 5. One single, unreplicated, chromosome
- 6. Spindle fibers are responsible for evenly splitting chromosomes during meiosis. When chromosomes are not split evenly, this is called __________ and causes chromosomal disorders.
- 8. The chromosomes that end up in each gamete are different and were randomly sorted there. This is called __________ assortment.
- 10. The overall production of different combinations of genes in homologous chromosomes due to crossing over.
- 12. Type of syndrome that is caused by the presence of an extra "X" chromosome. Can only occur in males
- 13. Type of cells in the body other than sperm and egg cells are called _______ cells. This includes blood cells.
- 14. Cells with two sets of chromosomes- one from each parent. Represented by "2n".
- 16. Type of syndrome that is caused by the absence of an "X" chromosome. Can only occur in females.
- 19. When two homologous chromosomes connect before crossing over.
