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 synapsis. Synapsis begins before the synaptonemal complex develops and is not completed until near the end of prophase … Nettet7. jan. 2016 · At any one point along a chromosome, the process of exchange (crossing over) involves only two of the four chromatids in a meiotic tetrad. Late in prophase I, crossovers become visible as chiasmata. Linked genes can be mapped on a chromosome by studying how often their alleles recombine.
