Chiasmata are most clearly visualised in which stage?
Answers
Chiasmata are the visible effects of the process of genetic crossing over between chromosomes which have paired up (i.e . between bivalents) in appropriately stained meiotic cells and hence indicators of recombination. They are best visible at the diplotene stage of prophase I of meiosis I.
Answer:
Here's your answer.
Explanation:
prophase I
Chiasmata are the visible effects of the process of genetic crossing over between chromosomes which have paired up (i.e . between bivalents) in appropriately stained meiotic cells and hence indicators of recombination. They are best visible at the diplotene stage of prophase I of meiosis I.
prophase I of meiosis
The chiasmata become visible during the diplotene stage of prophase I of meiosis, but the actual "crossing-overs" of genetic material are thought to occur during the previous pachytene stage.
