Polyembryo

But sour and swee oranges have a number of characters in common -- small-panicled inflorescences, tight peel, whitish polyembryo, etc.

A complicating feature of conifers, when estimating the number of lethals, is that polyembryos are common during seed development.

This method is effective because unlike other fructiferous plants, citrus possesses the polyembryo property, thus obtaining from a single seed more than one plant with identical properties to the parent plant.

Mitochondria, like the phospholipids, have been investigated when the polyembryo of Ageniaspis had the form of a tube (string).

The phenomenon, nevertheless, is probably greatly underreported, because to my knowledge no one has searched methodically—using suitable nuclear genetic markers—for vertebrate polyembryos in nature.

Furthermore, in certain species having polyembryos development (e.g., armadillo), all the embryos that have develope from a single fertilized egg are of the same sex.
