Meiosis occurs in a series of different phases and creates genetically unique reproductive cells. Which process helps make meiotic cells genetically different and occurs during prophase I, but not during prophase II?
fertilization
independent assortment
crossing over
chromosome replication

Meiosis occurs in a series of different phases and creates genetically unique reproductive cells. The process which helps make meiotic cells genetically different and occurs during prophase I, but not during prophase II, is crossing over (C). Crossing over is the exchange of genetic material between two homogenous chromosomes. It is one of the final phases of prophase I. This process is called synapsis. It occurs when the matching regions on the matching chromosomes break and then reconnect to the other chromosome .
