polyembryony

In plants, polyembryony often gives rise to the enigma of a single offspring.

Polyembryony occurs regularly in many plants and animals.

Embryo development and polyembryony in relation to the phylogeny of conifers.

A related phenomenon, polyembryony is a process that produces multiple clonal offspring from a single egg cell.

He discovered polyembryony in the 1930s while working on Litomatix truncatellus Hymenoptera.

This is the only regular case of 'polyembryony' in the class Mammalia, where one fertilised egg splits into four embryos.

The 'Paradox' of Polyembryony: A review of the cases and a hypothesis for its evolution.

There are a number of polyploid species known as the S. cernua complex, which are characterized by apomixis and polyembryony.

Polyembryony among Abietineae.

The phenomenon of polyembryony (formation of more than one embryo in the seed) is known to occur in this variety.

Monoembryony Polyembryony also occurs in Bryozoa.

A more striking example of the use of polyembryony as a competitive reproductive tool is found in the parasitoid Hymenoptera family Encyrtidae.

Some species exhibit a remarkable developmental phenomenon called "polyembryony", in which a single egg multiplies clonally in the host and produces large numbers of identical adult wasps.

This is the only reliable manifestation of polyembryony in the class Mammalia, and only exists within the genus Dasypus and not in all armadillos, as is commonly believed.

During the development of seeds from plants that possess this genetic trait, the nucellar tissue which surrounds the megagametophyte can produce additional embryos (polyembryony) which are genetically identical to the parent plant.

Modern cyclostomes exhibit polyembryony: fertilised ova divide to produce multiple, genetically identical larvae which are housed in the spacious gonozooid before being released, swimming for a short period before settling and undergoing metamorphosis to establish new clonal colonies.
