Polyembryony in Oenothera

1988
In Oenothera twin plants, two embryos in one seed, occur. They were observed in our own cultures and known to other geneticists working with this genus, like W. STUBBE and earlier RENNER (personal communication by STUBBE), but received no special attention.

Experimental Polyembryony in Mammals

1987
Natural polyembryony is an extremely rare occurrence in mammals although the incidence of identical individuals is unknown in most species because generally they go unnoticed. The nine-banded armadillo (Dasypus novemcinctus) usually has monozygotic quadruplets and the eleven-banded armadillo (Dasypus hybridus) has between 7 and 12 (usually 8) identical

POLYEMBRYONY IN EUGENIA HOOKERI

American Journal of Botany, 1936
EUGENIA HOOKERI is a fairly common ornamental in the Los Angeles region of Southern California, where, when allowed to grow freely, it becomes a tree 15 to 25 feet or more high, with somewhat glossy oblanceolate, acuminate leaves and clusters of light to dark purple or dark wine-colored fruit. When mature the fruit measures 1.5 to 1.7 cm. in length and

Polyembryony in Encyrtid Parasitoids

2019
The phenomenon of polyembryony in insects was first recognized by Marchal (1898) in the chalcidoid family Encyrtidae. This large family of small, solitary egg–larval endoparasitoids includes 460 genera, two of which exhibit polyembryony: Ageniaspis and Copidosoma (Ivanova-Kasas 1972).
