Thus, in humans, it is a measure of fertility in a man. An egg cell lives only 12 to 24 hours in her own environment and cannot be preserved. This process, called recombination or 'crossing over', shuffles the genetic information - two stretches of DNA that were near each other on one chromosome may end up in different egg or sperm cells. Is it damage the power of thinking? Mistakes are more likely to happen, and they will build up as the message gets passed along.
