Correct answer: B. Synapsis starts
- A. Recombinant
- B. Synapsis starts
- C. Tetrad
- D. Bivalent
Explanation
The first essential phenomenon of meiosis i.e. pairing of homologous chromosomes called synapsis starts. This pairing is highly specific and exactly pointed but with no definite starting points. It allows the matching-up of homologous pairs before their segregation, and possible chromosomal crossover between them.
