Questions and Answers 100% Pass

What are the phases of meiosis I? - ANSWER✔✔-Prophase I, Metaphase I, Anaphase I,

Telophase I


What is the role of meiosis I? - ANSWER✔✔-Reduce the number of chromosomes by

half


What are the phases of meiosis II? - ANSWER✔✔-Prophase II, Metaphase II, Anaphase

II, Telophase II


What is the role of meiosis II? - ANSWER✔✔-Separate sister chromatids so each

daughter cell gets one copy


Identify three differences between meiosis I and meiosis II. - ANSWER✔✔-Interphase-

DNA copied before meiosis I; DNA not copied before meiosis iiProphase i -

synapsis/crossing over ; Prophase II- no synapsis/crossing overAnaphase I-

homologous chromosomes separate; Anaphase II - chromatids separate


Identify what part of meiosis results in the reduction of chromosome number. -

ANSWER✔✔-Separation of homologous partners during anaphase I so each daughter

cell gets either a maternal or paternal chromosome not both for each of the 46

, What are the phases of mitosis? Describe each phase. - ANSWER✔✔-Prophase-

Chromatin condenses into chromosomes Nuclear membrane disappears Mitotic

spindle/centrosomes appear and attach to chromosomesMetaphase- Homologous

chromosomes line up independently in middle of cellAnaphase- Chromatid copies

separate and chromosomes move to opposite poles of cellTelophase- Chromosomes

spread out as chromatin Nuclear membrane reforms Mitotic spindle/centrosomes

disappear


Describe the daughter cells resulting from mitosis. - ANSWER✔✔-2 diploid daughter

cells, genetically same as parent and each other


Describe the daughter cells resulting from meiosis. - ANSWER✔✔-4 haploid daughter

cells, genetically different from parent cell and different from each other


Identify three similarities between mitosis and meiosis. - ANSWER✔✔-1. Both are

preceded by a growth period called interphase , in which a cell replicates its genetic

material and organelles in preparation for division. 2. Both mitosis and meiosis involve

phases: Prophase, Metaphase, Anaphase and Telophase3. Both use same cellular

machinery- centrosomes/mitotic spindle/motor proteins to move chromosomes.


Identify three differences between mitosis and meiosis. - ANSWER✔✔-MITOSIS


Diploid (2n) parent cell produces TWO genetically identical DIPLOID (2n) daughter

cells


Produces body (somatic) cells
