During fertilisation in plants the male and female gametes unite, triggering the process of cell division followed by seed formation. A gene , expressed only in the male gamete, is responsible for eliciting rapid cell division. A researcher overexpressed the gene in the female gamete that resulted in the multiplication of the female gamete into an embryo and then the seed. The plants obtained from these seeds were genetically identical to the parent. This phenomenon is commonly seen in a few select plants naturally, and is known as
(a)Aneuploidy
(b)Polyembryony
(c)Allogamy
(d)Apomixis
