Question

Development of seed from an unfertilised egg is called as

• A. Vivipary
• B. Parthenocarpy
• C. Apomixis
• D. Apospory

Answer 1

The correct option is C Apomixis

Apomixis was defined by Hans Winkler as replacement of the normal sexual reproduction by asexual reproduction, without fertilization. Apomixis is the development of seed from maternal genotype only. Apomictically produced offspring are genetically identical to the parent plant. Male apomixis (paternal apomixis) involves replacement of the genetic material of the egg cell by that from the pollen.

Vivipary is the condition whereby the embryo are developed inside the parent.

Parthenocarpy, development of fruit without fertilization e.g., pineapple, banana, cucumber, grape, orange, grapefruit, persimmon etc.

Apospory is the production of sexual generation from an asexual generation without the intervention of spores. Thus, the correct answer is option C.
