Question

The organism develops from a female gamete/egg without fertilization

• A. Polyembryony
• B. Adventive embryony
• C. Parthenogenesis
• D. Parthenocarpy

Answer 1

The correct option is C

Parthenogenesis

The correct option is C.

Explanation for correct option:

1. Parthenogenesis is the development of an embryo from an egg without fertilization.
2. Parthenocarpy is the process of fruit formation without fertilization.

Explanation for incorrect options:

Option A:

1. Polyembryony is a condition in which one egg develops into two or more embryos.
2. In this situation, a single egg produces two or more genetically identical offspring.
3. It is seen in both plants and animals (including humans, where it results in the birth of identical twins).

Option B:

1. Adventive embryonic development is the process of embryonic development without fertilization.
2. The embryo does not develop from reproductive cells or gametes.
3. They can develop from nucellus or integumentary cells.

Option D:

1. Parthenocarpy is the production of fruits without fertilization of the ovule.
2. Fruits like bananas and figs develop without fertilization and do not produce any viable seeds.
3. The stage in which fruits develop without seeds is called parthenocarpy.

Final Answer: The development of an organism from a female gamete/egg without involving fertilization is parthenogenesis.
