Dr. Josh is a scientist who studies the genetic traits of plants. He prefers growing plants though pollination, a form of sexual reproduction, rather than growing them form cuttings. Why does he prefer this method?

The options are:
It is easier to generate a new plant through pollination than through cuttings.
Pollination provides more genetic variation than cuttings.
Pollination is a faster method of reproductive than cuttings.
Pollination increases the number of genes an individual inherits.
Pollination is a definite method of reproduction.
