The process of MITOSIS 1. Where does it occur? a. In somatic areas 2. How many Cycles or divisions occur? a. One cycle of prophase through telophase 3. What is its major purpose? a. Provides constant supply of new cells for growth, maintenance, replenishment of worn cells 4. Is it the basis for any type of reproduction? a. Yes, all asexual 5. How many daughter cells are produced? a. Two 6. What is the final chromosome number of the daughter cells? a. Same as the mother cell before mitosis began 7. What do daughter cells become? a. Replacements of old cells and new cells for growth and maintenance 8. What important major events occur during division as noted above in #7 9. Is genetic variation caused by this type of division? a. No The Process of MEIOSIS 1. Only in diploid (2n) germ cells in the sex organs of sexually reproducing animals 2. Two series of divisions, a first followed by a second division. Meiosis in NOT a cycle 3. Provides constant supply of gametes (sperm and eggs) for continuation of

Unformatted text preview: the species through sexual reproduction. 4. Yes sexual in that it produces gametes 5. Four 6. One-half that of the mother cell: daughter cells have been reduced from diploid to haploid (2n to n) 7. Gametes (sperm and eggs) used for sexual reproduction. 8. Synapsis, crossing over, independent assortment and segregation, all important meiotic events. 9. Normally, yes, mainly due to synapsis, crossing over, and independent assortment. For each of the following, choose the answer from the list on the right 1. Diploid cell produces haploid cell 2. Crossing over occurs 3. Occurs in ovaries and testies 4. Homologous chromosomes separate 5. Sister Chromatids separate 6. Process involves two divisions of the “nucleus” 7. Process only involves one division of the “nucleus” 8. Produces identical daughter cells A. Mitosis only B. Meiosis only C. Both D. Neither...
