Biology Question on Meiosis
The process of appearance of recombination nodules occurs at which sub stage of prophase I in meiosis?
A
Pachytene
B
Diplotene
C
Diakinesis
D
Zygoten
Answer
Pachytene
Explanation
Solution
Recombination nodules, also known as synaptonemal complex, play a crucial role in the crossing-over and recombination of genetic material between homologous chromosomes. Pachytene is the stage of prophase I during which homologous chromosomes are closely paired and synapsed, and recombination nodules become visible under microscopy.
Therefore, The correct option is (A): Pachytene
