d
Anaphase
QuestionChoice
The G2 phase occurs after DNA replication (S phase) and is mainly associated with further preparation for cell division (mitosis). It is not a phase where genetic variation is introduced but rather one where the cell ensures that it is ready for mitosis.

G2 phase
QuestionChoice
Telophase is the fifth and final phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. There is no introduction of genetic variation during this phase.

Telophase
QuestionChoice
During pachytene in prophase 1, genetic information is exchanged between homologous pairs of chromosomes at the chiasmata. This is an example of genetic variation being introduced as the chromosomes come from 2 genetically unique individuals.

a
Pachytene
QuestionChoice
This is the first phase of prophase during which the chromosomes just begin to condense. There is no "crossing over" yet and thus no introduction of genetic variation.
