Use the following key to answer the following questions. Each answer may be used once, more than once, or not at all.
A. The statement is true for mitosis only.
B. The statement is true for meiosis I only.
C. The statement is true for meiosis II only.
D. The statement is true for mitosis and meiosis I.
E. The statement is true for mitosis and meiosis II.
46.__ Sporophytic plant cells produce the 4 haploid spore cells.
47.__ Dyads are aligned on the equatorial plate of cell.
48.__ Cell division occurs and the cells produced have the haploid number of chromosomes.
The following questions refer to the essential steps in meiosis described below.
1. formation of 2 new nuclei, each with n numberchromosomes present
2. alignment of dyadsat the metaphase plate
3. separationof sister chromatids
4. separationof the homologs; no uncoupling of centromeres
5. synapsis; tetrad “chromosomes” moving to the middle of the cell in pairs
49.__ From the descriptions above, which of the following is the orderthat most logically illustrates a sequence of meiosis?
A) 5, 4, 2, 3, 1 B) 5, 4, 1, 2, 3 C) 5, 3, 2, 4, 1 D) 4, 5, 2, 1, 3 E) 5, 2, 4, 3, 1
50.__ Which of the steps take place in only meiosis and not in mitosis?
A) 1,2, and 3
B) 1,2,4, and 5
C) 1,4, and 5
D) 2 and 3 only
E) 2,3, and 5
Explanation / Answer
For 40-42 no figure is provided.
Ans 43. Metaphase 1 it is stage in meiosis when tetrad alignment occur at metaphase plate. For each tetrad kkinetochore microtubules from one pole of the cell are attached to one homologous chromosome,and other kinetochore tubule from another pole of cell. So option B is correct.
Ans.44 Anaphase II in this phase dyads pulled apart into monads and these monads are moves to opposite poles of cell. So option E is correct.
Ans. 45 Anaphase II in which segregation occur result in haploid. E correct.
