In apomictic seed bearers, several embryos are formed within the seed
(polyembryony). One is the result of sexual reproduction and will
have shared genes from both parent plants, the remainder will have
been produced asexually and be clones of the mother plant. This is
most commonly demonstrated in several Citrus species - the clonal
seedlings being noticeable more vigorous and easily identified. When
apomictic germination occurs, it is a useful means of reproducing the
mother plant without having to worry about hybrid variation.
