Can sexual reproduction create new genetic information? Is there a small chance that in sexual reproduction a new allele forms in the off-spring that was not present in either of the parents, or are the alleles in the offspring always from at least one of the parents? Is new genetic information ever created during sexual reproduction, or only through mutations during an organisms life time?

Homologous Recombination not only shuffles different mutations together, but similar sequences near each other from gene duplication events and from regions with highly repetitive sequences can recombine and cause gross changes in the sequence of the genome in hot spots.
