Chromosomal hybrid, or crossing over, is the trading of hereditary material during sexual multiplication between two homologous chromosomes' non-sister chromatids that outcomes in recombinant chromosomes.
It is one of the last periods of hereditary recombination, which happens in the pachytene phase of prophase I of meiosis during a cycle called synapsis.
Synapsis starts before the synaptonemal complex creates and isn't finished until close to the furthest limit of prophase I.
Hybrid normally happens while matching areas on matching chromosomes break and afterward reconnect to the next chromosome.
Getting over and DNA fix is very much like cycles, which use a considerable lot of similar protein edifices.
