The visible cross shaped points at which homologous chromatids have exchanged segments are called
- A. chiasmata
- B. centromeres
- C. kinetochores
- D. telomeres
Explanation
Chiasmata can be seen under the microscope in prophase one and mark where crossing over has occurred. The centromere is the chromatid junction and the kinetochore its spindle attachment, neither of which involves exchange.
