Linkage: meaning, definitions and examples

Used in formal contexts, especially in scientific or technical fields to describe things that are connected or related in a specific way.

• The genetic linkage between the two traits was well-documented in the study

A broad term used in a wide range of contexts to describe anything from physical links to emotional bonds or logical relations.

• He felt a deep connection with the city where he grew up

Often used in personal, emotional, or interpersonal contexts to describe how people or entities are related to each other.

• The relationship between the two friends has grown stronger over the years

Applies in contexts where there is a more general connection, often used in everyday language and in social or organizational scenarios.

• There is a strong association between smoking and lung cancer

Used broadly to describe the connection or relationship between two or more things. Often used in various scientific, technical, or mechanical contexts.

• The report discusses the linkage between climate change and global economic prospects.
• The engineers are examining the linkage system to ensure it operates smoothly.

Used specifically in genetics to describe the tendency of genes that are close together on a chromosome to be inherited together. Commonly used in genetic mapping studies.

• Genetic linkage studies have helped identify genes that contribute to hereditary conditions.
• Understanding genetic linkage helps scientists map out gene locations on chromosomes.

Used in genetics to describe a statistical relationship between genetic variants and particular traits or diseases. Often used in studies and research papers.

• The recent study found a genetic association between certain DNA markers and the risk of developing diabetes.
• Researchers are investigating the genetic association of these traits with various cognitive functions.

Another context is when describing a chain of interconnected parts or a system.

• A complex linkage of laws governs this process.
• The linkage of events led to the discovery.

Applicable when making a general reference to any type of connection that is mechanical in nature, not limiting to a specific part or function.

• Inspect the mechanical connection before starting the engine.
• The integrity of the mechanical connection is vital for safety.

This term is suitable when referring to a single point where two parts come together, often allowing for movement or flexibility.

• The knee joint is crucial for leg movement.
• Make sure the joint between the two pipes is secure.

Best used to describe the connection between two things, often to ensure they work together smoothly. It’s commonly used in engineering and mechanical contexts.

• A flexible coupling is used to connect the motor to the pump.
• The coupling of the two pipelines is done with special care.
