Term
| What is the difference in chromosome number between regular body cells and gametes or sex cells? |
|
Definition
| regular body cells are diploid(2n) and have 46 chromosomes and sex cells are haploid(n) and have 23 chromosomes. |
|
|
Term
| What is meant when the symbol 2n is used? What is meant when the symbol 1n is used? Be sure to use the terms haploid and diploid. |
|
Definition
| 2n means that a cell has two sets of chromosomes (diploid), one from each parent. N means that the cell contains only one set of chromosomes. |

| What is the synaptonemal complex and when does it disappear? |
|
Definition
| The synaptonemal complex is a protein structure that forms between two homologous chromosomes during meiosis and disappears during late prophase. |
