These flashcards can help you study for the Meiosis test on Feb 14th and 15th.

| 315323843 | Diploid | A body cell: 2 copies of every chromosome | 0 | |
| 315323844 | Haploid | A gamete (sperm or egg cell) that contains half the DNA of a body cell. | 1 | |
| 315323846 | Crossing-over | Crossing over is when genetic information is exchanged between homologous chromosomes. This exchange creates new combinations of genes, leading to increased genetic variation in the offspring. | 2 | |
| 315323847 | End result of Meiosis | 4 gametes | 3 | |
| 315408943 | Gamete | a haploid reproductive cell that unites with another haploid reproductive cell to form a zygote | 4 | |
| 315408944 | Interphase | a period before meiotic divisions during which the cell grows, copies its DNA, and synthesizes proteins | 5 | |
| 315408945 | Prophase I | Each chromosome pairs with its corresponding homologous chromosome to form a tetrad. | 6 | |
| 315408946 | Metaphase I | The second phase of meiosis I. the paired homologous chromsomes (tetrads) align at the center of the cell (the metaphase plate). | 7 | |
| 315408947 | Anaphase I | The third phase of meiosis I. the replicated homologous chromosomes are separated (the tetrad is split) and pulled to opposite sides of the cell. | 8 | |
| 315408948 | Telophase I | Chromosomes move all the way to the other side of the cell and two new cells are ultimately formed. | 9 | |
| 315408949 | Prophase II | The first phase of meiosis II. Prophase II is identical to mitotic prophase, except that the number of chromosomes was reduced by half during meiosis I. | 10 | |
| 315408950 | Metaphase II | chromosomes line up at the equator | 11 | |
| 315408951 | Anaphase II | Sister chromatids are separated and pulled to opposite sides of the cell. | 12 | |
| 315408952 | Telophase II | 4 cell results....each cell is haploid with unreplicated chromosomes | 13 | |
| 315408953 | The order of phases in Meiosis | Interphase, Prophase I, Metaphase I, Anaphase I, Telophase I, Prophase II, Metaphase II, Anaphase II, Telophase II | 14 | |
| 315408954 | How many cell divisions occur during Meiosis? | 2 | 15 | |
| 315408955 | How many total cells are produced at the end of Meiosis? | 4 | 16 | |
| 315408956 | Interphase |  | 17 | |
| 315408957 | Prophase I |  | 18 | |
| 315408958 | Metaphase I |  | 19 | |
| 315408959 | Anaphase I |  | 20 | |
| 315408960 | Telophase I |  | 21 | |
| 315408961 | Prophase II |  | 22 | |
| 315408962 | Anaphase II |  | 23 | |
| 315408963 | Metaphase II |  | 24 | |
| 315408964 | Telophase II |  | 25 | |
| 315408965 | Spindle Fibers | These fibers do all of the pulling and separation of chromosomes during Meiosis. | 26 | |
| 315408966 | A | Which picture shows a possible gamete? |  | 27 |
| 315408967 | Homologous Pair | a pair of chromosomes, one from each parent, that have relatively similar structures and gene values |  | 28 |
