Pairing of homologous chromosomes during zygotene in meiosis is:
Correct answer: B. Highly specific and exactly pointed
- A. Non specific but exactly pointed
- B. Highly specific and exactly pointed
- C. Non specific and non pointed
- D. Highly specific but fused
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 point (s.) Each paired but not fused, complex structure is called a bivalent or tetrad.
