Meiosis Practice & Mitosis Comparison (per. 1)

Meiosis Video Watch the meiosis video and then answer the questions below. 1. Steps of meiosis Match each phase of meiosis to the correct description. Prophase I Homologous chromosomes pair up and form tetrad. Crossing over occurs. Anaphase I Spindle fibers move homologous chromosomes to opposite sides Telophase II Nuclear membrane reforms, cytoplasm divides, 4 daughter cells formed Metaphase II Chromosomes line up along the equator, not in homologous pairs Anaphase II Chromatids separate Prophase II Centrioles move to opposite ends and spindle fibers form in two the two daughter cells Metaphase I Homologous pairs line up along the equator Telophase I Cytoplasm divides, 2 daughter cells are formed 2. Phases of meiosis Label the pictures with the correct PHASE OF MEIOSIS. - Use I or II. NOT 1 or 2 (ex. anaphase I)**In the last blank, put the steps in order using the numbers.** 3, 4, 1, 6, 7, 5, 2, 8 Anaphase I Anaphase II Metaphase I Metaphase II Telophase I Prophase I Prophase II Telophase II Amoeba Sisters - Mitosis vs. Meiosis: Side by Side Comparison Watch the video below to answer the following questions. 3. Fill in the blanks using the information from the video. * Meiosis is a type of cell division that makes sex cells or gametes.* The female sex cells are eggs and the male sex cell is sperm.* Mitosis consists of one division(s), while meiosis consists of of two division(s).* Mitosis makes the cells with the same number of chromosomes as the parent cell, but meiosis produces cells with half the number of chromosomes as the parent cell.* A human's body cells have 46 chromosomes; sex cells, or gametes, have 23. 4. Fill in the blanks using the information from the video. * For every chromosome your mother gave you, there is a homologous chromosome from your father with information regarding the same trait(s)* When a cell has a full complement of homologous chromosomes from each parent (two complete sets of chromosomes), the cell is said to be diploid.* Sex cells have only one set of chromosomes, they are said to be haploid.* When an egg and a sperm combine during fertilization the zygote that is formed has the normal diploid number of chromosomes.*Homologous chromosomes exchange information during meiosis which adds to diversity.
