8. Can you recall meiosis and indicate at what stage a recombinant DNA is made?

Meiosis is a process that involves a reduction in the amount of genetic material. It is two types, namely meiosis I and meiosis II.

During the pachytene stage of prophase I, crossing over of chromosomes takes place where the exchange of segments between non-sister chromatids of homologous chromosomes takes place. This results in the formation of recombinant DNA.
