Mitosis and Meiosis
Preguntas del test (10)
1Mitosis and meiosis are processes involved in cellular reproduction. Which of the following describes an event that results from mitosis but NOT meiosis?
- ATwo stages of cell division
- BReplication of cellular genetic material
- CDaughter cells that are identical to the parent cell
- DFour daughter cells that are produced from each parent cell
2Which type of reproduction leads to increased genetic variation in a population?
- AParthenogenesis
- BAsexual reproduction
- CSexual reproduction
- DVegetative reproduction
3Which of the following best compares the processes of mitosis and meiosis?
- AMitosis involves one division cycle and results in diploid daughter cells, while meiosis consists of two division cycles and results in haploid gametes
- BMitosis involves one division cycle and results in haploid gametes, while meiosis consists of two division cycles and results in diploid daughter cells
- CMitosis involves two division cycles and results in diploid daughter cells, while meiosis consists of one division cycle and results in haploid gametes
- DMitosis involves two division cycles and results in haploid gametes, while meiosis consists of one division cycle and results in diploid daughter cells
4Which of the following best explains why meiosis results in greater genetic diversity than mitosis?
- AAfter meiosis, daughter cells are diploid and have twice as much genetic material, which can be divided in many more possible combinations
- BAfter meiosis, haploid daughter cells are fertilized, which doubles the number of chromosomes and increases the number of possible genes
- CDuring meiosis, chromosomes assort themselves independently of each other, which allows for more different possible combinations of chromosomes
- DDuring meiosis, more daughter cells are produced, which increases the likelihood that fertilization will occur
5Which of the following occurs during mitosis?
- AThe cell membrane pinches one cell into two
- BThe chromosomes of the patient cell are copied
- CThe parent cell takes in nutrients and doubles in size
- DThe nucleus of the parent cell divides into two nuclei
6In a single celled organism, mitosis is used for:
- ADevelopment
- BReproduction
- CGrowth
- DRepair
7Multicellular organisms use mitosis for growth, development and:
- AApoptosis
- BRepair
- CReproduction
- DInterphase
8Why is it important for the daughter cells to divide a second time in meiosis?
- AThe second division switches parts of matching chromatids to increase genetic variation
- BThe second division forms four identical cells to ensure that all offspring have the same traits
- CThe second division sorts chromosomes into cells that are the same as the parent cells
- DThe second division forms haploid cells that can combine with other haploid cells during fertilization
9What happens to sister chromatids in meiosis II?
- AThey duplicate
- BThey separate
- CThey remain together
- DThey do not take part
10Which of the following describes how the process of crossing over during meiosis leads to an increase in genetic diversity?
- ADuring prophase I, DNA replication takes place and homologous chromosomes trade places with each other before lining up in preparation for metaphase
- BDuring prophase I, DNA segments are exchanged between homologous chromosomes resulting in different combinations of alleles
- CDuring prophase II, fragments of DNA break off of chromosomes and attach to the ends of other chromosomes, resulting in different gene sequences
- DDuring prophase II, sister chromatids separate from each other, and as they travel to oppsite ends of the cell, DNA segments of nearby chromosomes are exchanged
