Process: Pairing of Homologous Chromosomes: Homologous chromosomes (one from each parent) pair up, forming tetrads. Synapsis: The homologous chromosomes align closely together, allowing for the exchange of genetic material. Chiasmata Formation: Points where the chromosomes overlap and exchange segments are called chia schromosomes cross over Exchange of Gen
