mitosis and meiosis
Term | Definition |
---|---|
Gametes | an egg or sperm cell; a sex cell |
Cytokinesis | the division of the cell cytoplasm the usually follows mitotic or meiotic division of the nucleus |
Haploid | single/simple |
Gametogenesis | the development of gametes |
Chromosomes | a structure in all living cells that consist of a single molecule od DNA bonded to various proteins and that carries the games determining heredity |
Gonad | a sex gland in which gametes are produced; an ovary or testis |
Polar bodies | one of the minute cells arising from the unequal meiotic of the ovum at or the time of fertilization |
Ovum/ova | female reproductive cell or gamete of plants |
Centromere | a specialized structure on the chromosomes, appearing during cell division as the constricted central region where the two chromatids are held together and form an x shape |
Crossing over | interchange of corresponding chromatid segments of homologous chromosomes with their linked genes |
Tetrad | a group or set four |
Synapsis | the pairing of homologous chromosomes one each parent, during early meiosis |
Interphase | the stage a cell between two successive mitotic division |
Diploid | double; twofold |
Chromatin | the readily stainable of a nucleus, consisting of DNA, RNA, and various proteins, that forms chromosomes during cell division |
Replication | to copy |
chromatid | one f two identical chromosomal strands into which a chromosome splits longitudinally prepared for cell division |
