|---|---|---|---|---|---|
| Interphase | show 🗑
|
||||
| show | The first stage in the first meiotic division of meiosis It highlights the exchange of DNA between homologous chromosomes via a process called homologous recombination and the cross-over at chiasma(ta) between non-sister chromatids.
🗑
|
||||
| show | Homologous chromosomes pair with each other to form tetrads of four chromatids and they align themselves along a single plane in the centre of the cell. This stage ends as soon as the homologous chromosomes start being pulled away from each other.
🗑
|
||||
| Anaphase 1 | show 🗑
|
||||
| show | The stage in the first meiotic division of meiosis that follows anaphase I. The two sets of chromosomes have finished moving to opposite ends of the cell. Cytokinesis occurs, forming two daughter cells.
🗑
|
||||
| Prophase 2 | show 🗑
|
||||
| show | during which the chromosomes are aligned along a single plane in the centre of each cell produced during the first meiotic division (two total cells). Each chromosome can clearly be observed as a pair of joined, identical chromatids.
🗑
|
||||
| show | in each cell produced during the first meiotic division, the paired chromatids are separated from each other and moved to opposite ends of the cell. The stage begins as soon as the centromeres connecting each chromatid to its pair break and ends.
🗑
|
||||
| show | The two sets of chromosomes have finished moving to opposite ends of each of the two cells produced during the first meiotic division. Cytokinesis occurs, resulting in four haploid cells.
🗑
|
||||
| show | ChiasmaThe point of contact between paired chromatids during meiosis, resulting in a cross-shaped configuration and representing the cytological manifestation of crossing over like the letter X.
🗑
|
||||
| show | A process occurring during meiosis wherein two chromosomes pair up and exchange segments of their genetic material.
🗑
|
||||
| Chromatid | show 🗑
|
||||
| Bivalents | show 🗑
|
||||
| show | The pairing of homologous chromosomes during the meiotic phase of cell division
The act of lining up side by side by homologous chromosomes during the meiotic phase of cell division
🗑
|
||||
| show | The random lining up or chromosomes during meiosis.
🗑
|
||||
| show | A reproductive cell or sex cell that contains the haploid set of chromosomes, e.g. spermatozoon or sperm cell (male reproductive cell) and egg cell or ovum (female reproductive cell).
🗑
|
||||
| show | A chromosome is a long, stringy aggregate of genes that carries heredity information (DNA) and is formed from condensed chromatin.
🗑

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.
