Crossing Over & Gene Linkage: Definition, Importance & Results

Crossing Over• In meiosis after replication of the chromosomes, the chromosomes go through a phase ofcrossing-over (recombination) during which alleles on homologous chromosomes (one from themother and one from the father) are randomly shuffled.• Crossing over results from pieces of the chromosome breaking off and switching with the sameportions on its homologous chromosome.• This results in genetic mixing/shuffling, which ultimately leads to increased variation.In the diagram below are two homo
