When the embryos develop without fertilisation?

Solution (By Examveda Team)

When the embryos develop without fertilization is called parthenogenesis, not given in the option.
Parthenogenesis is a natural form of asexual reproduction in which the growth and development of embryos occur in a gamete without combining with another gamete.
Parthenogenetic offspring in species that use either the XY or the X0 sex-determination system have two X chromosomes and are female.
