The two main sources that lead to increased genetic variation are gamete mutations and recombination.
A gamete is the cell which combines with another cell during fertilization. So, its mutation can lead to variation in genes. Recombination as well, as the position of genes is changed.

Answer:

The correct answer is recombination.
