The statement that accurately describes the process of crossing over is that crossing over occurs after replication and non-sister chromatids exchange gene segments to make new combinations of genes. So, the correct option is B.
What is Crossing over?
Crossing over is a process through which there is an exchange of genetic material between non-sister chromatids of a homologous chromosome.
After the replication process, the amount of genetic content gets doubled and arranged in the form of chromatids. Two chromatids of the same chromosomes are known as sister chromatids. And those two chromatids of homologous chromosomes are known as non-sister chromatids.
Therefore, crossing overs occurs after replication, and non-sister chromatids exchange gene segments to make new combinations of genes.
