Definition
| Cell division in diploid cells thatresults in haploid cells. |
|
|
Term
|
Definition
| The haploid cells that fuse with other haploid cells to form zygotes; the sperm or egg cells. |
|
|
Term
|
Definition
| The fusion of the male and female gametes. |
|
|
Term
|
Definition
| The diploid cell resulting from the fusion of two gametes. |
|
|
Term
|
Definition
| A pair of chromosomes having the same size and shape and carrying alleles for the same traits. |
|
|
Term
|
Definition
| Having two sets of chromosomes or all of the homologous chromosomes that are characteristic of the same species. |
|
|
Term
|
Definition
| an organism or cellhaving any one complete set of chromosomes, ordinarilly half the normal diplod number. |
|
|
Term
|
Definition
| the period of the cell cycle during which the nucleus is not undergoing division, typically occurring between mitotic or meiotic divisions. |
|
|
Term
|
Definition
| In prophase I the chromosomes become visible. |
|
|
Term
|
Definition
| The pairs of chromosomes (bivalents) become arranged on the metaphase plate and are attached to the now fully formed meiotic spindle. |
|
|
Term
|
Definition
| In anaphase I the chromatids holding the chromosomes together loosen. The two homologous chromatids of each tetrad are separated into separate poles. |
|
|
Term
|
Definition
| the final stage of meiosis or mitosis, in which the separated chromosomes reach the opposite poles of the dividing cell and the nuclei of the daughter cells form around the two sets of chromosomes. |
|
|
Term
|
Definition
| the pairing of homologous chromosomes, one from each parent, during early meiosis. |
|
|
Term
|
Definition
| a group of four chromatids formed by synapsis at the beginning of meiosis. |
|
|
Term
|
Definition
| The nuclear membrane and nuclei break up while the spindle network appears. Chromosomes do not replicate any further in this phase of meiosis |
|
|
Term
|
Definition
| If needed, the nuclear membrane and nuclei break up while the spindle "network" appears and the chromosomes begin migrating to the metaphase II plate (at the cell's equator). |
|
|
Term
|
Definition
| The sister chromatids of each chromosome separate and move toward opposite poles. The poles themselves move further apart. |
|
|
Term
|
Definition
| the sister chromatids reach opposite poles, cytokinesis occurs, the two cells produced by meiosis I divide to form four haploid daughter cells, and nuclear envelopes form. |
|
|
Term
|
Definition
| the interchange of corresponding chromatid segments of homologous chromosomes with their linked genes. |
|
|
Term
|
Definition
| temporary union or permanent fusion as a form of sexual reproduction in certain algae and fungi, the male gametes of one organism uniting with female gametes of the other. |
|
|
Term
|
Definition
| the act of disjoining or the state of being disjoined: a disjunction between thought and action. |
