Why does meiosis tend to give rise to greater diversity more quickly than asexual reproduction?

Answer 1

When you make exact carbon copies of genetic material, diversity only occurs when a mis-copy occurs as opposed to a regular basis. This is how asexual reproduction creates new creatures.

Meiosis leads to gametes which are cells with only half of the genetic information from the original cell. When that is combined with half of the genetic information from a different creatures gametes, the resultant creature is different from both parents every time. This is how sexual reproduction creates diverse creatures at every iteration.
