Term | Definition |
mitosis vs. meiosis | 1. genetically identical/genetically unique 2. result = diploid cells/result = haploid cells 3. asexual/sexual 4. one cell division/two cell divisions |
meiosis I | divides homologous chromosomes, produces two haploid cells |
prophase I | centrioles and centromeres move to opposite sides and homologous chromosomes pair up |
metaphase I | pairs of chromosomes line up randomly in the middle by spindle fibers |
anaphase I | pairs of chromosomes separate towards opposite sides of the cell |
telophase I | nuclear membrane forms around two separate cells, cytokineses (separation of cytoplasm) |
meiosis II | divides sister chromotids, resulting in haploid cells (DNA is not copied before-hand) |
prophase II | centrioles and centromeres move to opposite sides, nuclear membrane breaks down |
metaphase II | individual chromosomes line up in middle by spindle fibers |
anaphase II | sister chromatids are pulled apart towards opposite sides |
telophase II | cytokinesis, nuclear membrane reforms around the four individual haploid |
somatic cells | cell that makes up all of the body tissue and organs, except gametes |
gametes | sex cell (egg or sperm) |
homologous chromosomes | chromosomes that have the same length, appearance, and copies of genes, although the alleles may differ |
autosome | chromosome that contains genes for characteristics not directly related to the sex of the organism |
sex chromosome | chromosome that directly controls the development of sexual characteristics (determines male or female) |
sexual reproduction | process by which two gametes fuse and offspring that are a genetic mixture of both parents are produces |
fertilization | fusion of an egg and sperm cell |
diploid | cell that has two copies of each chromosome |
haploid | cell that has one copy of each chromosome |
meiosis | divides diploid cells into haploid cells, forming gametes |
polar body | haploid cell produces during meiosis in the female of any species |
