| Term | Definition |
|---|
| genes | segments of DNA on a chromosome |
| 46 | number of chromosomes human body cells have |
| 23 | number of chromosomes each parent cell (sperm or egg) contributes |
| homologous | chromosomes that make up a pair (one chromosome from each parent that codes for a trait) |
| gametes | sex cells |
| meiosis | reduction-division process that forms gametes; involved in genetic variation in organisms |
| interphase | cells carry out various metabolic processes including the replication of DNA and the synthesis of proteins |
| anaphase I | homologous chromosomes separate and migrate toward opposite poles |
| prophase I | synapsis occurs and crossing over can happen between homologous chromosomes |
| metaphase I | pairs of homologous chromosomes line up at the center of the cell and spindle fibers attach to the centromere of homologous chromosomes |
| anaphase II | sister chromatids are pulled apart at the centromere by the spindle fibers and move toward opposite poles |
| 4 unidentical cells | the end result of meiosis |
| 2 identical cells | the end result of mitosis |
| body cells | where mitosis occurs |
| 2 sets of divisions | meiosis |
| 1 set of divisions | mitosis |
| asexual reproduction | organism inherits all of its chromosomes from a single parent |
| crossing over | causes genetic variation in meiosis |
