Biology Question on cell cycle and cell division
Arrange the following events of meiosis in a proper sequence and select the correct option. I. Terminalisation II. Crossing over III. Synapsis IV. Disjunction of genome
A
IV, III, II and I
B
III, II, I and IV
C
II, I, IV and III
D
I, IV, III and II
Answer
III, II, I and IV
Explanation
Solution
Synapsis occurs during zygotene stage. Crossing over during pachytene stage and terminalisation during diakinesis. These three stages occur in prophase I and disjunction of genome, where homologous chromosomes break their connection and separate out occurs during anaphase I.
