Meiosis I |
The first division of a two-stage process of cell division in sexually reproducing organisms that results in cells with half the chromosome number of the original cell. |
|
Meiosis II |
The second division of a two-stage process of cell division in sexually reproducing organisms that results in the cells with half the chromosome number if the original cell. |
|
Synapsis |
The pairing of replicated homologous chromosomes during prophase I of meiosis. |
|
Crossing over |
The reciprocal exchange of genetic material between nonsister chromatids during prophase I of meiosis. |
|
Tetrad |
A paired set of homologous chromosomes, each composed of two sister chromatids. Tetrads form during prophase I of meiosis. |
|
Chiasma |
The X-shaped, microscopically chromatids that have exchanged genetic material through crossing over during meiosis. |
|
Recombinant Chromosome |
A chromosome created when crossing over combines the DNA from two parents into a single chromosome. |
