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.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
