In a given homologous chromosome pair, two recombinant chromatids are generated by a single crossover event.
Homologous chromosomes are the chromosomes that possess the same genes at the same loci and also have the same structure. One chromosome of the homologous pair is paternal while the other is maternal. Crossing over even takes lace between homologous chromosomes only.
Crossing over is the event that involves the interchange of genetic material between homologous chromosomes. Due to this event, the offspring receives genes from both the parents. The exchange of genetic material occurs between two non-sister chromatids in crossover, hence two recombinants are obtained.
