Included Quiz Questions
A cell biologist examines a skin cell from a lizard during metaphase of mitosis and determines that 20 chromatids are present. Which of the following are correct regarding the sex cells of this same animal? (Check all that apply.)
- They produce 4 daughter cells that are genetically different from each other
- They produce 4 daughter cells that are genetically different from the original parental cell
- They reduce the number of chromosomes per cell from 10 to 5
- They reduce the number of chromosomes per cell from 20 to 10
Which of the following is true of germ line cells?
- They are diploid in nature
- They are haploid in nature
- They are polyploid in nature
- They are triploid in nature
- They are tetraploid in nature
The meiosis division has what?
- Two nuclear divisions with one round of DNA synthesis
- Four nuclear divisions with one round of DNA synthesis
- Two nuclear divisions with two rounds of DNA synthesis
- Four divisions with two rounds of DNA synthesis
- Four nuclear divisions with four rounds of DNA synthesis
Which of the following is NOT correct regarding meiosis?
- The mature human sperm and egg contain 23 and 46 pairs of chromosomes in them, respectively
- Meiosis is a reductional division which reduces the chromosome number in the gametes cells by half to that of the parent cell
- Meiosis plays an important role in the sexual reproduction of the eukaryotic organisms
- Meiosis-I involves the segregation of homologous chromosomes; whereas meiosis-II involves the separation of sister chromatids
- Meiosis-I is reductional division; on the other hand, the meiosis-II division is equational
