Self pollination occurs when
grains from a flowering fall into
the pistils the same plant and
gametes from the same unite
to form a . Cross pollination
occurs when carry pollen
grains from plant to reach other
plants of the same
thus gametes of different
form the zygote.

Since promotes formation of zygotes
genes from different
individuals ( gene combinations)
cross pollination more to
biological diversity.
