In the cells of a human male body, the number of autosomes is :

1. 23 pairs
2. 22 pairs
3. 1 pair
4. 46 pairs

The basis of genetic variation in the living organisms during mitosis occurs due to :

1. Cell division
2. Mutation
3. Crossing over
4. Karyokinesis

The correct sequence of phases in interphase is:

1. G₁, G₂ and S
2. S, G₂ and G₁
3. G₁, S and G₂
4. G₂, S and G₁

The phase of karyokinesis which is almost the reverse of prophase is :

1. Interphase
2. Metaphase
3. Anaphase
4. Telophase
