Other plants, especially weeds such as hawkweed and dandelions, can produce true seeds that are clones of themselves without sexual reproduction -- a still poorly understood process called apomixis.
Other key topics include reproduction, renewal, propagation, amphimixis, apomixis, reproductive effort, reproductive success, potential seed productivity, and real seed productivity.

Barring apomixis, the only explanation is that I accidentally disrupted an anther sac in the process of removing a stamen from the flower.
Through so-called "terminator technology," biotech corporations such as Monsanto, Dupont, and Novartis have transferred the apomixis gene, inducing the trait of asexual reproduction, into agricultural plants.
