Recombination is the combination of genetic material from chromosomes, shuffling genes during meiosis. In this case, it is being compared to shuffling and recombining aspects of an edited digital image. | Recombination is the combination of genetic material from chromosomes, shuffling genes during meiosis.

Other changes remove or degrade from the genetic history, without apparent detriment, just because the circumstances do not currently confer any significant advantage to it. If the 'lost' ability is perhaps useful in dealing with an infrequent environmental stress then the loss of its utility might be felt a generation or two later. |
With recombination, useful novel changes can be shuffled into the population without necessarily bringing in a less useful mutation, creating descendents with both the obvious advantages (a sword) and the previously more established resilience (the fuller frame). | With recombination, useful novel changes can be shuffled into the population without necessarily bringing in a less useful mutation, creating descendents with both the obvious advantages (a sword) and the previously more established resilience (the fuller frame). |
