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.
