The two chromosomes contain the same genes, but may have different forms of the genes.
Chromosomal crossover, or crossing over, is the exchange of genetic material during sexual reproduction between two homologous chromosomes ' non-sister chromatids that results in recombinant chromosomes. It is one of the final phases of genetic recombination, which occurs in the pachytene stage of prophase I of meiosis during a process called ...
Crossing Over. During meiosis, when homologous chromosomes are paired together, there are points along the chromosomes that make contact with the other pair. This point of contact is deemed the chiasmata and can allow the exchange of genetic information between chromosomes. This further increases genetic variation. There are also many other ways in which genetic variation is increased in a ...
