hybridisation
Học thuậtThân thiện
Definition
Noun: 1. (Genetics) The act or process of crossing different species or varieties of organisms to produce offspring (hybrids) with combined characteristics. This is a controlled biological process used in agriculture, horticulture, and scientific research.
Usage
- Hybridisation is a key technique in modern agriculture to develop crops with desirable traits like disease resistance or higher yield.
- The term is most precisely used in scientific contexts, particularly genetics and biology.
Examples
- The hybridisation of two distinct rose varieties resulted in a new flower with a unique color and fragrance.
- Scientists studied the natural hybridisation between two closely related species of fish in the lake.
- The hybridisation program aimed to combine the hardiness of one wheat strain with the high grain quality of another.
Advanced Usage
- Molecular hybridisation: A laboratory technique where complementary strands of DNA or RNA bind together. This is a different, specific application of the core concept of "combining different elements."
- Fluorescent in situ hybridisation (FISH) is a crucial cytogenetic technique.
Variants and Related Words
- Hybridize (verb): To perform or undergo hybridisation.
- Farmers hybridize plants to improve their characteristics.
- Hybrid (noun): The offspring resulting from hybridisation.
- A mule is a hybrid of a horse and a donkey.
- Hybridity (noun): The state or quality of being hybrid.
Synonyms
- Crossbreeding
- Crossing
- Interbreeding (specifically between different species or varieties)
Notes on Meaning
- The core concept is the mixing or combining of distinct types to create something new. While its primary and most precise use is in biology, the term can be used metaphorically in other fields (e.g., the hybridisation of cultures or musical genres) to describe a similar process of blending.
Noun
- (genetics) the act of mixing different species or varieties of animals or plants and thus to produce hybrids
