The development of organisms from female gametes without fertilisation is called
Parthenogenesis
In some organisms like rotifers, honey bees and even some lizards and birds (turkey), the female gamete undergoes development to form new organisms, male and/or female, without fertilisation. This phenomenon is called parthenogenesis.
Polyembryony is the formation of more than one embryo from a single fertilized ovum.
Parthenocarpy involves formation of fruit without seed production.
Polygamy is a pattern of mating in which an animal has more than one mate.
