KROK 1 2017 – Question 159 · KROK (Medicine) · Biology
Students study the stages of gametogenesis. They analyze a cell with haploid number of chromosomes, with each chromosome consisting of two chromatids. The chromosomes are located in the equatorial plane of the cell. Such situation is typical of the following stage of meiosis:
- A. Prophase of the first division
- B. Metaphase of the second division
- C. Anaphase of the second division
- D. Anaphase of the first division
- E. Metaphase of the first division
Hint
Compare the chromosome number and the state of the chromatids with what each meiotic stage has already accomplished, and note where the chromosomes are positioned.
The answer, the explanation and a note on every option are available once you log in. The account is free: topic tests, a mock exam, mistake review and statistics.
