Answer: This crossing-over process results in an unlinking and recombination of parental genes. ... Subsequently, recombination by itself does not cause evolution to occur. Rather, it is a contributing mechanism that works with natural selection by creating combinations of genes that nature selects for or against.
Recombination is an event, occurring by the crossing-over of chromosomes during meiosis, in which DNA is exchanged between a pair of chromosomes. ... Like mutation, recombination is an important source of new variation for natural selection to work upon.
