Question

Development of an embryo without fertilization is called as

• A. Apomixis
• B. Polyembryony
• C. Parthenocarpy
• D. Parthenogenesis

Answer 1

The correct option is D Parthenogenesis

Development of an embryo directly from an egg cell without fertilization is called as parthenogenesis. Parthenogenesis occurs naturally in many plants, some invertebrate animal species (including nematodes, water fleas, some scorpions, aphids, some bees and parasitic wasps).

Apomixis is an asexual mode of seed formation that produces clonal progeny with a maternal genotype.

Polyembryony is the phenomenon of two or more embryos developing from a single fertilized egg.

Parthenocarpy is the natural or artificially induced production of fruit without fertilization of ovules.

Hence, option D is correct.
