The following events occur during the process of meiosis. Arrange the following events of meiosis in the correct sequence. I. Terminalization II. Crossing over III. Synapsis IV. Disjunction of genomes
1 I, II, III, IV
2 II, III, IV, I
3 III, II, I, IV
4 IV, I, II, III
Explanation:
The correct sequence of the events in the meiosis is: III, II, I, IV. III. Synapsis: Synapsis is the pairing of two homologous chromosomes that occurs during meiosis. It allows matching-up of homologous pairs prior to their segregation, and possible chromosomal crossover between them. It occurs in zygotene sage. II. Crossing over: Crossing over is exchange of chromosomes segments between non-sister chromatids of homologous pair. Crossing over occurs during pachytene stage. I. Terminalization: Terminalization of chiasmata occurs in diakinesis stage of meiosis I. It is the disappearance of chiasmata of sliding towards the tips of the chromosomes due to tight condensation. IV. Disjunction of genomes: The process of breakdown of homologous chromosomes is called disjunction. This process occurs in anaphase I.
