Question | Answer |
Metaphase 1 | During Metaphase 1, spindle fibers attach to the chromosomes. The homologous chromosomes align at the equator of the cell. |
Name the different phases of Meiosis 2 in order. | Prophase 2, Metaphase 2, Anaphase 2, Telophase 2, and Cytokinesis |
Gametes | Gametes are egg and sperm. |
What is the production of egg cells called? | Oogenesis |
What is a diploid number and what is a haploid number? | A diploid number is a term used to a cell that contains both sets of homologous chromosomes. A haploid cell that contains only a single set of chromosomes. |
Name the different phases of Meiosis 2 in order. | Prophase 2, Metaphase 2, Anaphase 2, Telophase 2, and Cytokinesis |
Prophase 1 | During Prophase 1, each chromosome pairs with its corresponding homologous chromosome to form a tetrad. |
Metaphase 1 | During Metaphase 1, spindle fibers attach to the chromosomes. The homologous chromosomes align at the equator of the cell. |
Tetrads | Tetrads are the two homologous chromosomes that are attached together. Also called synapsis. |
Anaphase 1 | During Anaphase 1, the fibers pull the homologus chromosomes toward opposite ends of the cell |
Telophase 1 | During Telophase 1, nuclear membranes form, and the the cell separates into two genetically different cells. |
Prophase 2 | Nuclear envelope fragments, and the spindle forms. |
Metaphase 2 | Chromosomes align along the equator of the cell. |
Anaphase 2 | Sister chromatids separate and move to opp. poles of the cell. |
Telophase 2 | The nuclear envelope assembles ad chromosomes de-condenses and the spindle disappears. |
Cytokinesis | divides the cell into two, resulting into four haploid daughter cells |
Homologous | A term used to refer to chromosomes that each have a corresponding chromosome from the opposite sex parent |
Chromatids | A chromatid is one of the two identical sister parts of a duplicated chromosome. |
Alleles | One of the numbers of the different forms of a genes. |
Somatic Cells | Body Cells |
