Question

The true statement about apomixis is, it is a type of reproduction resulting in development of:

• A. An embryo from endosperm
• B. An embryo from nucellus
• C. A new organism from fusion products of gamets
• D. A new organism without fusion of gamets

Answer 1

Answer:

D. A new organism without fusion of gamets

• Apomixis is a type of asexual reproduction in plants where seeds and embryos develop without fertilization, i.e., without the fusion of male and female gametes. This process results in offspring genetically identical to the parent plant.

• Option (a) "An embryo from nucellus" refers to adventitious embryony, which is a specific form of apomixis but not the general definition.

• Option (b) "An embryo from endosperm" is incorrect because the endosperm serves as nutritive tissue, not the embryo.

• Option (c) "A new organism from fusion products of gametes" describes sexual reproduction, not apomixis.
