| Differences between Meiosis and Mitosis. |
|
Definition
1) There is an extra phase in Meiosis.
2) There are four off-springs
3) There is two interphases in Meiosis
4) In one of Meiosis' interphase there is no DNA being made. |

Definition
| The ability of a single gene to affect an organism in many ways. |
|
|
Term
|
Definition
| An additive effect of two or more genes on a single phenotypic trait. |

Term
|
Definition
| Interphase (not actually at rest, but making more Deoxyribonucleic Acid (DNA)) |
|
|
Term
| First Phase of Mitosis (and What's happening?) |
|
Definition
| Prophase- Centrosomes separate, start moving towards opposite poles, creating early mitotic spindle. Chromatin starts forming chromosomes. |
|
|
Term
| Second Phase of Mitosis (and What's happening?) |
|
Definition
| Prometaphase- Centrosomes are now at opposite ends of the cell. Nuclear membrane starts dissolving. Kinetocores latch onto chromosomes. |
|
|
Term
| Third Phase of Mitosis (and What's happening?) |
|
Definition
| Metaphase- Nucleus is completely dissapeared by now. The double stranded chromosomes line up at the metaphase plate. |
|
|
Term
| Fourth Phase of Mitosis (and What's happening?) |
|
Definition
| Anaphase- Double stranded chromosomes are pulled apart. |
|
|
Term
| Last Phase of Mitosis (and What's happening?) |
|
Definition
| Telophase- Cells are being pulled apart, cleave furrow is forming in animals, a cell wall is forming in plant cells. Nucleus begins to form, nucleolus does too. |
|
|
Term
|
Definition
| The point in mitosis and meiosis that the cell is dividing. |
|
|
Term
|
Definition
| Two cells coming together forming one cell. The purpose of this is to have Variety. |
|
|
Term
|
Definition
| A cell copying itself creating an exact copy. |
|
|
Term
|
Definition
| random segregation of alleles to separate gametes |
|
|
Term
|
Definition
| More than one of the other forms of a gene that come from a mutation that are on the same place on the chromosome. |
|
|
Term
| Law of Independent Assortment |
|
Definition
| chromosomes segregate separately from other nonhomologous chromosomes |
|
|
Term

Term
|
Definition
