| In all these groups cloning, where it occurs, must be through polyembryony or parthenogenesis. |
| A characteristic feature of gymnosperms is polyembryony manifested in the formation of more than one embryo in immature seed. |
| Despite their utility in research, litters produced by polyembryony lack the advantages conferred by either asexual or sexual reproduction. |
| On arriving in Texas, he spent most of his research efforts studying polyembryony, first in the armadillo, and then in various parasitic wasps. |
| Within the sporocyst, a special form of asexual reproduction, known as polyembryony, then occurs. |
| By its nature, that is whether it develops with or without fertilization, simple polyembryony can be sexual or asexual. |
