Mutation: meaning, definitions and examples

This term is often used in the context of biology or genetics to describe a change in the DNA sequence. It can refer to naturally occurring changes or those induced by environmental factors.

• Scientists discovered a mutation in the gene that could lead to a new form of resistance to the virus

This term is generally used to refer to the diversity in gene frequencies within a population, which can be the result of mutations, genetic recombination, and other factors.

• Genetic variation is crucial for the survival of a species as it provides the raw material for evolution

This phrase is more technical and is often used in medical or scientific discussions about deliberate changes to genetic material, such as through genetic engineering or gene therapy.

• Genetic alteration in crops can increase their resistance to pests and improve yield

Best used in a scientific or biological context to describe a change in the genetic material of an organism.

• The researchers studied the effects of the genetic mutation on the development of the fruit flies.
• The mutation caused the plant to produce larger flowers than usual.

Used in a linguistic context to describe changes in the sounds of speech over time within a language.

• The phonetic change in the pronunciation of vowels is evident in different dialects of English.
• Historical phonetic change altered the way Old English words are spoken today.

Can be used in various contexts to describe changes or adaptations in wording, including linguistics, literature, or everyday communication.

• Word alteration often occurs when translating text from one language to another.
• The poet's clever word alteration added a playful tone to the poem.

Used primarily in a biological or genetic context to describe a change in the DNA sequence that may lead to different traits or characteristics.

• The scientists studied the mutation to understand how it affects the butterfly's wing color.
• Genetic mutations can sometimes result in diseases.

Often used in a medical or scientific setting to describe something that deviates from the normal structure or function, implying a potential issue or problem.

• The X-ray showed an abnormality in the patient's lung.
• They are conducting tests to find any abnormalities in the baby's development.

Generally used to describe differences or deviations in a set of data, traits, or characteristics. It implies a range of normal differences rather than something inherently negative.

• There is a lot of variation in the color of these flowers.
• The study looked at the genetic variation among different populations.
