Meiosis Vocab
Term | Definition |
---|---|
Asexual Reproduction | Reproduction that does not involve the union of gametes and in which a single parent produces offspring that are genetically identical to the parent |
Clone | An organism that is produced by asexual reproduction and that is genetically identical to its parent; to make a genetic duplicate. |
Crossing over | the exchange of genetic material between homologous chromosomes during meiosis; can result in genetic recombination |
Meiosis | A process in cell division during which the number of chromosomes decreases to half the original number by two divisions of the nucleus, which results in the production of sex cells(gametes or spores) |
tetrad | the four chromatids in a pair of homologous chromosomes that come together as a result of synapsis during meiosis |
nondisjuntion | the failure of homologous chromosomes to seperate during meiosis I or the failure of sister chromatids to separate during mitosis or meiosis II |
synapsis | the pairing of homologous chromosomes during meiosis |
Electrophoresis | The process by which electrically charged particles suspended in a liquid move through the liquid because of the influence of an electric field. |
Haploid | describes a cell, nucleus, or organism that has only one set of unpaired chromosomes. |
Diploid | a cell that contains two haploid sets of chromosomes. |
Independent Assortment | the random distribution of the pairs of genes on different chromosomes to the gamete |
Homologous Chromosomes | chromosomes that have the same sequence of genes, that have the same structure, and that pair during meiosis |
