|---|---|---|---|---|---|
| heredity | the passing of genetic traits from parent to offspring
🗑
|
||||
| asexual | formed by, characterized by, or being a process of reproduction (as the dividing of one cell into two cells) that does not involve the combining of male and female germ cells
🗑
|
||||
| reproduction | the process by which living things produce offspring
🗑
|
||||
| gene | one set of instructions for an inherited trait
🗑
|
||||
| DNA (deoxyribonucleic acid) | a molecule that is present in all living cells and that contains the information that determines the traits that a living thing inherits and needs to live
🗑
|
||||
| chromesomes | in a eukaryotic cell, one of the structures in the nucleus that are made up of DNA and protein; in a prokaryotic cell, the main ring of DNA
🗑
|
||||
| dominant trait | the trait observed in the first generation when parents that have different traits are bred
🗑
|
||||
| recessive trait | a trait that is apparent only when two recessive alleles for the same characteristic are inherited
🗑
|
||||
| alleles | one of the alternative forms of a gene that governs a characteristic, such as hair color
🗑
|
||||
| genotype | the entire genetic makeup of an organism; also the combination of genes for one or more specific traits
🗑
|
||||
| phenotype | an organism's appearance or other detectable characteristic
🗑
|
||||
| meiosis | a process in cell division during which the number of chromesomes decreases to half the original number by two divisions of the nucleus, which results in the production of sex cells (gametes or spores)
🗑
|
||||
| mitosis | in eukaryotic cells, a process of cell division that forms two new nuclei, each of which has the same number of chromesomes
🗑
|
||||
| Interphase | Longest phase, cell grows, DNA is copied, (Chromesomes are copied.)
🗑
|
||||
| Prophase | Chromesomes condense from long strands to rod like structures.
🗑
|
||||
| Metaphase | Nuclear Membrane dissolves. Paired chromatids line up at cells equator.
🗑
|
||||
| Anaphase | Chromatids separate and move to the opposite sidesof the cell.
🗑
|
||||
| Telophase | Nuclear membrane forms around each set of chromesomes. Chromesomes unwind.
🗑
|
||||
| Cytokinesis | Cells without a cell wall separate into two new daughter cells.
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
