KROK 1 2018 – Question 171 · KROK (Medicine) · Biology
Genetic recombination is achieved via several mechanisms. One such mechanism is crossing-over. It occurs at the following stage of prophase in the first meiotic division:
- A. Leptonema
- B. Pachynema
- C. Zygonema
- D. Diplonema
- E. Diakinesis
Hint
Put the substages of prophase I in order and relate crossing-over to the events of homologue pairing and the later appearance of chiasmata.
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.
