Transfer of pollen occurring in the same flower is known as ______.

Appeared in: RRB Nsg. Superintendent - 29 April 2025 (Shift-3rd)

Explanation

Self-pollination is the correct term for the transfer of pollen grains from the anther to the stigma of the same flower.
This specific type of self-pollination is called autogamy.
It results in offspring with low genetic variation as the genetic material comes from a single parent plant.

Option A: Hybridization is the process of creating a hybrid by crossing two genetically different individuals, which may be from different species or varieties. It is a broader concept than just the transfer of pollen.
Option B: Cross-pollination involves the transfer of pollen between flowers of two different plants of the same species.
Option D: Fertilization is the fusion of the male and female gametes to form a zygote. It is the step that occurs after successful pollination, not the process of pollen transfer itself.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Types of Pollination as background academic context rather than a clinical decision trigger.
This is a fundamental concept in botany and general biology, not directly related to clinical nursing practice.
Understanding genetics and reproduction, even in plants, provides a foundational knowledge base that can be helpful when studying more complex human genetics and reproductive health.
What if the question was about human reproduction? The analogous process to pollination would be insemination (the deposition of sperm), and the analogous process to fertilization would be the fusion of sperm and egg.

How to Approach the Question

First, identify the key phrase in the question: 'transfer of pollen occurring in the same flower'.
Define each of the options in your mind.
Self-pollination: Pollen transfer within the same flower or plant.
Cross-pollination: Pollen transfer between different plants.
Fertilization: Fusion of gametes (egg and sperm).
Hybridization: Crossing of different species/varieties.
