|---|---|---|---|---|---|
| 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
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
