The problem the justice was thinking about
however is that this decision will affect
all the other kinds too, unless they word
it very specifically not to.[ Reply to This | Parent | # ]

A lot of plants have "complete" flowers and are CAPABLE of
self-pollination. But in nature this is fast track to extinction! It makes a lot
of sense for *some* of your seeds to be self-pollinated, but not all, maybe even
not most.
In many such plants, the ?stamens (the female part) matures first, to be
hopefully pollinated by other plants. Then the ?pistils mature later,
fertilising any remaining unfertilised stamens, along with a lot of other plants
that have matured a bit later on.
The *ability* to self-fertilise is a valuable survival tactic. To make
preferential use of it is suicide.
Nature does not like in-breeding ...
