Options
- A( a ) ( i i ) ( b ) ( i ) ( c ) ( i i i ) ( d ) ( i v )
- B( a ) ( i i ) ( b ) ( i i i ) ( c ) ( v ) ( d ) ( i v )
- C( a ) ( i ) ( b ) ( i i ) ( c ) ( v ) ( d ) ( i v )
- D( a ) ( i i ) ( b ) ( i i i ) ( c ) ( i v ) ( d ) ( v )
Correct answer
B. ( a ) ( i i ) ( b ) ( i i i ) ( c ) ( v ) ( d ) ( i v )
Step-by-step solution
Synapsis of homologous chromosome - Zygotene. Synthesis of RNA & protein - G 2 phase. Action of enzyme recombinase - Pachytene. Centromeres do not separate but chromatid move towards opposite pole - Anaphase-I. In Anaphase-II, the centromere splits and each half chromosome moves to opposite poles.
