Topic: NEET PYQ
Answer: B. Full step-by-step solution below.
- ADiakinesis
- BPachytene
- CZygotene
- DDiplotenes
Correct answer: B
Solution
(b) The first two stages of prophase I are relatively short-lived compared to the next stage that is pachytene. During this stage the four chromatids of each bivalent chromosomes became distinct and clearly appears as tetrads. This stage is characterized by the appearance of recombination nodules, the site at which crossing over occurs between non-sister chromatids of the homologous chromosomes.More Cell Cycle & Cell Division PYQs
